That picture on the wall is going to drive me crazy if it is not straight.
Someone bumped me on my left side, and now things are uneven.
Going and straightening a picture, even if it is not yours or it is not an opportune time to do it (such as in the middle of a meeting).
Following that person and bumping into him or her on the right side to make things even.
I have to make an equal number of left and right turns on my way home, or something bad might happen.
I cannot work unless I straighten up my desk, because all I will think about is my messy desk.
Going out of your way on the way home in order to get in an equal number of turns.
Straightening your desk for several hours each day at the expense of your work productivity.
