In the summer of 2011, a 22-year-old country singer from Prince Edward Island stayed up most of the night rehearsing her speech.

Meaghan Blanchard was practising with such determination because she would be performing in front of Prince William and his wife Catherine during their first official royal tour of Canada.

When the big night arrived, nerves got the best of Blanchard and the by blurting out 鈥淒ootch鈥 instead of 鈥淒uke and Duchess鈥. Luckily, the gracious couple laughed off the unfortunate gaffe and Blanchard鈥檚 subsequent musical performance went smoothly.

To help you avoid an embarrassing fate similar to Blanchard鈥檚, CTV鈥檚 royal commentator, Richard Berthelsen, has shared some helpful tips with CTVNews.ca on the Dos and Don鈥檛s of meeting their Royal Highnesses.

The Duke and Duchess of Cambridge and their adorable children, Prince George and Princess Charlotte, will be embarking on a from Sept. 24 to Oct. 1.

The Royal Family has more than 30 engagements planned and they are expected to meet thousands of Canadians along the way.

What to do when greeting the Royal Family:

Be polite:

Berthelsen says that commoners used to be expected to wait until they were spoken to by a member of the Royal Family before they could address them. Today, however, Berthelsen says members of the Royal Family are much more easygoing and happy to have conversations with civilians.

鈥淧eople today have a much more free-flowing engagement with them,鈥 he told CTVNews.ca.

If one of the royals asks you a question during your encounter, Berthelsen said it鈥檚 perfectly acceptable to ask them a question in return, as long as it鈥檚 polite.

Some Canadians will have the opportunity to be formally presented to the royal couple during the tour and in that case, a more traditional tone may be required. During an official ceremony, Berthelsen recommends that you address both the Duke and Duchess of Cambridge as 鈥淵our Royal Highness鈥 the first time and then Sir or Ma鈥檃m in future references. He also said that men can greet them with a nod from the neck and women can do a slight curtsy.

A handshake will do:

When it comes to physical contact with the royals, Berthelsen stresses that handshakes are the only acceptable form of touching. He said there is always someone from the public who manages to put their arm around one of the members of the Royal Family during a tour and the media, particularly the British media, makes a big deal about it. One example of this was when basketball star, LeBron James, during her visit to New York City in 2014.

鈥淲e feel like we know them, but we don鈥檛 really know them,鈥 he said. 鈥淭hey are owed a little bit of distance, a little bit of respect because of their position.鈥

Children, on the other hand, are an exception to the handshake rule. Berthelsen said the royals are very good with children, especially Kate. There is usually a designated official flower girl at many of the events the royals attend and the Duchess will usually hug the little girl and engage with her.

鈥淐atherine, of course, has that affinity with children being a mom of two young kids herself,鈥 he said.

Be prepared:

During the Canadian tour, the Duke and Duchess will be received by a number of different hosts at various stops along the way. If you鈥檙e lucky enough to be hosting the royal couple during the tour, Berthelsen said you should prepare in advance what you would like to tell the royal couple about the facility or organization you鈥檙e representing.

鈥淭hey (the hosts) want to be a little light and not too lecturing about what鈥檚 going on,鈥 he said. 鈥淜eep it fun, keep it amusing and keep it short.鈥

Berthelsen also recommends that hosts come up with a few amusing anecdotes about their organization and community to provide a memorable experience for the visiting Royal Family members.

Practising your bow or curtsy is also not a bad idea if you know you will be presented to the Duke and Duchess during an official ceremony.

What NOT to do when greeting the Royal Family:

Absolutely no selfies:

As tempting as it might be to snap a quick selfie with Prince William or his wife Kate, Berthelsen said it isn鈥檛 recommended. He says the Royal Family, especially Prince Harry, don鈥檛 like taking selfies with fans because they usually take longer to frame than a regular photo, which takes time away from others who are also waiting to meet them.

鈥淭hey鈥檙e happy to have people take pictures of them,鈥 Berthelsen said. 鈥淏ut in terms of them posing and getting in a photo with their arm around you, it鈥檚 probably not going to happen.鈥

No elaborate gifts:

If you don鈥檛 want to show up emptyhanded when you first meet the Royal Family, Berthelsen suggests bringing flowers as a gift. He said that sometimes the flowers go back to where the royals are staying but more often than not, they are donated to local hospitals or hospices.

But giant teddy bears, homemade presents or tacky framed photos are best avoided, he added. He says Prince George and Princess Charlotte have more than enough toys and the Duke and Duchesses are often embarrassed by the amount of gifts they receive during their public visits.

鈥淚t鈥檚 going a little too far,鈥 He said. 鈥淔lowers are one thing, but beyond that, people should really avoid investing heavily in gifts.鈥

Berthelsen says the royals are very tactful when they鈥檙e greeting crowds by pretending not to notice the elaborate gifts to avoid dealing with them afterwards.

As long as you鈥檙e polite and respect the Royal Family鈥檚 personal space, you shouldn鈥檛 run into any problems. But if you鈥檙e particularly anxious, practising your 鈥淒uke and Duchess鈥 one more time might not be the worst idea.
