If you are invited to an American friend’s home for dinner, remember these general rules for polite behavior. First of all, arrive approximately on time but not early. Americans expect promptness. It will be all right to be 10 or 15 minutes late, but not 45 minutes late. When you are invited to someone’s home for meal, it is polite to bring a small gift. Flowers and candy are always appropriate. If you have something attractive made in your country, your host or hostess will certainly enjoy receiving that gift. What will you do if you are served some food that you cannot eat or you do not like? Do not make a fuss about it. Simply eat what you can and hope that no one notices it. Be sure to compliment the cook on the food that you are enjoying. Do not leave immediately after dinner, but do not overstay your welcome, either. The next day, call or write a thank-you note to say how much you enjoyed the evening.
