5. Rules to follow when going to a party
In the United States and Canada, people often invite friends to their homes for a meal or a party. Here are some simple rules to follow:
When someone invites you to dinner, do not bring anyone with
you because this would cause problems with the amount of food
provided. Your host will tell you if you can bring a guest, such as
your husband or wife.
When someone invites you to a large or informal party, you can
often bring a friend. But for smaller parties, always call your host
first to ask if it’s OK.
When leaving a party, thank the host for a good time and often
make excuses for leaving “so early”, even if it isn’t early.
Question:
Do you often invite friends home for dinner? Is it OK to bring a friend to dinner? To a party? Is there any other rules to follow?
