     If you are invited to someone’s house for dinner in the United States, you should bring a gift, such as a bunch of flowers or a box of chocolates. If you give your host a wrapped gift, he/she may open it in front of you. Opening a present in front of the gift-giver is considered polite. It shows the host is excited about receiving the gift and wants to show his/her appreciation to you immediately. Even if the host doesn’t like it, he/she will tell a “white-lie” and say how much they like the gift to prevent the guest from feeling bad. If your host asks you to arrive at a particular time, you should not arrive exactly on time or earlier than the expected time, because this is considered to be potentially inconvenient and therefore rude, as the host may not be ready.
