敲黑板:
1. DON’T BE ON TIME
Unless your host is the super prepared type (those people actually exist), it wouldn’t be a good idea to promptly pitch up at the arranged time. Usually, before guests arrive, the host hurriedly does the last preparations and so it is expected that he/she isn’t fully prepared at arrival time. Be a champ and arrive a little later, 15 minutes at the latest, though, as any time after that would be considered impolite.
