Due to meet friend at 5pm to have tea. She's already over 25 minutes late and didn't even get a bus until after our meeting time. This happens all the time with her. She knew I was in a rush and I'm in here sitting by myself when I could be getting the work done that I need to do tonight. Shall I walk out? She's a nice person but her disorganisation pisses me off as it's me that always ends up waiting. I've got 1000 things I could get done right now.
