Aaagh, why did I do this?

I and my two flatmates are having a party. I just sent out an invitation email, and it was so hard to decide who to invite from work! I keep thinking people will be like "why on earth did she invite me?" or "why didn't she invite that person?".

Why are we having a party, I don't know why I thought that was a good idea. But too late, I have sent the email. *hides under the desk*
