I tried to use the computer at the library yesterday for a bit (had to go there because I returned three things that were due on Tuesday but it said one thing wasn't returned, it turns out that they just didn't scan it as returned before putting it back on the shelf - there's no late fees at the library for overdue things anymore, but I didn't want them to mark the DVD as lost which means I would have to pay the cost for the item, although that's if an item is 30 days overdue IIRC, but I just wanted to get it dealt with) and wow I hate using other computers.
Like I have my keyboard set up in a very specific way, namely I used a piece of software to remap the caps lock key so it's instead backspace and I'm so used to being able to just hit that key to delete some text, I kept doing that on the library computer and just turning on all-caps.
