Forgetting to RSVP
If you receive an invite to an event, even if it’s on Facebook, it’s essential that you RSVP in a timely manner. Even if it seems like a relatively casual gathering, you’re making the host’s job harder by making them guess how many guests they can expect, or how much food or drink they should buy. And if there’s a formal RSVP card, make sure you mail it back with as much information as they’ve requested as soon as you have an answer.
