Party Planning

Saturday is my 19th birthday and I wanted to have a party. So, I decided to plan one for myself. One Friday night i will be going out to dinner and then to a club. On facebook made an event and invited 80 people. This was totally pointless because no one RSVP's accurately. It is crucial that I know exactly how many people. I've sent out and e-mail to everyone and only half of the people responded. Sometimes people are so rude and inconsiderate of other people's time! I have to make a dinner reservation by tonight and i still don't have a TOTAL! geeze o petes!
