What are some trivial things that annoy you?

Everything all of you have mentioned plus issues when building with stairs. Find it frustrating when trying to build a specific house I want and have to rearrange things such as stairs and windows because can't have windows over stairs. I want to be able to put windows by stairs and curtains on the windows without having to use MOO so they don't end up disappearing. Stairs require more room so sometimes have to make a house larger than planned to fit stairs where they should be. I would love to be able to have smaller staircases. Curtains are another issue as need to move windows so can place curtains, can't be near a door or chairs. Putting curtains on a diagonal window also an issue, only smaller curtains tend to work. The constant need to wash hands and drink water also is a problem for me as it cancels out actions I set for the sims to do. Sigh.
