Backdrop to why I was angry last night, underneath all main reasons.
Didn't have to make your own way there. Didn't have to get your own snacks and water. Didn't have to buy your own tickets (to a movie I'd said ages ago I didn't want to watch). Didn't have to dispose of your own garbage (even though the guy was just 2 metres away). Didn't have to navigate frustrating town traffic. So what did you do on your own last night?
Not angry anymore, just a thought that occurred to me just now as to why I got as upset as I did.
