Travelled abroad, you should follow the customs of the country where you are visiting. When you invited, it is good manners to refuse or accept the invitation, either by writing nor by telephoning. If you will go to the party, it is polite to arrive on time. It is good manners to shake hand with your host. You can bring a present if you like, possible a bottle of wine, a box of chocolates and some flowers. However, it was not bad manners to take nothing. It is not polite to stay too late before the other guests have gone. Also, it is suggested to write or telephone a day or two late to thank your host.
