What are some trivial things that annoy you?

Aight so one of my sim families doesn't have a bookshelf, but they have one book. Whenever anyone finishes reading, they automatically go to put it in the bookshelf. Since there is none, they wave their hand and put it on the floor. (Instead of say a table, which is part of what bugs me). However, their hands are still in the same position as if they were still holding the book and they refuse to start a new action until I reset them by shift clicking.

Another thing is guests kicking over the trashcan constantly. Especially Malcolm Landgraab.

Oh and when a teen ages up to young adult but their high school sweetheart is still a teen. I've aged them up manually a few times to compensate.
