HOW TO BE A WELCOME GUEST

Oh, for a guest like a British royal! “You can’t sit there with a stiff upper lip and not get involved,” said Prince Harry after his recent tour of the Caribbean. And he’s right—joining in is what being a good guest is all about, says Thomas Blaikie, author of Blaikie’s Guide to Modern Manners and columnist at The Lady magazine.

But there’s more to it than half-heartedly asking if there’s anything you can do. Etiquette is all about responding to a situation, says Blaikie, and only you can judge if it’s better to get the conversation flowing.

That’s difficult if you’re a house guest. “You may be on holiday but it’s not a hotel, so don’t leave the room in a mess as if you expect maids to appear,” says Blaikie. But don’t overdo it: washing up is fine, but washing the floor could be seen as a comment on your host’s hygiene. Bed linen is also tricky— should you strip the bed or make it before you leave? Best to ask the host, especially if you've only stayed one night.

Informality doesn't mean that any-thing goes. Monopolizing the host’s Wi-Fi, computer or bathroom is bound to irritate, so ask if it’s OK. “And texting to say you’re running late isn't the same as being punctual (within 15 minutes of the stated time),” says Blaikie. 

Saying thanks (an e-mail will do) is non-negotiable, as is eating what’s put in front of you—so if you’re on a restricted diet, offer to bring your own food. And don’t forget a gift. One good way of gifting is for a stay-in guest to take the host out to a meal at a restaurant they like.
