　　If you're invited to a friend's home for dinner, keep in mind these rules to be polite. First of all, arrive on time ( but not earlier). It's OK to be 10 or 15 minutes late but not 45 minutes. When you're invited to someone's home for a meal, it's polite to bring a small gift. Flowers or candy are always nice. If you have something made in your own country, your host(主人) would certainly enjoy receiving that as a gift most.

　　What do you do if you're served a food that you don't like or cannot eat? If your host doesn't say anything about what you aren't eating, then you shouldn't, either. Simply eat what you can and hope that no one sees what you left. If you are questioned, you may have to admit(承认) that you don't eat meat (or whatever), but you can also say that you've enjoyed the other foods and have had "more than enough" to eat.

　　Don't leave immediately (立即) after dinner, and don't stay too long, either. When your friends seem to be getting tired and running out of conversations, you'd better leave. The next day,call or write a thank-you note to say how much you enjoyed the evening.
