It is not polite to arrive at a dinner party more than 15 to 20 minutes 1 . The host or hostess usually waits for all the guests to arrive before serving the meal. If someone is late, the food may be spoiled, and so might the host or hostess’s spirits. If you have to be late, call and tell them to start 2 you.
It’s even 3 (bad) to be early! The host or hostess will probably not be ready. If you are early, drive or walk around the block a few times, or just sit in your car 4 the right time.
Though it is often important to arrive on time, yet on the other hand, for open houses, the host or hostess invites guests to arrive and leave 5 a certain time. You can arrive at any time within the time he or she gives you.
It’s polite to bring an empty stomach, but it’s even nicer to bring a small present. The present should not cost a lot, or you might embarrass the host or hostess. 6 (flower), wine, or a box of candy will do fine. Never bring money as a present.
