To celebrate my birthday, I invited everyone I know to join me for happy hour. I took the time to make and send a special invite. However, I was shocked by how many friends didn't read it. One person thought the party was the day I sent the invite, another went to the wrong bar, and two people showed up four hours after the specified time. Not reading an invitation is my biggest party planning pet peeve. I made it a point to provide all the necessary details, so why can't my guests take five seconds to read the text? Since we all host parties in some form or another, I'm sure you have party planning pet peeves, too.
So whether it's a guest that shows up empty handed or your roommate's uninvited friends crashing, do tell: When planning a party, what behavior bugs you?
