I took the middle of three urinals in an empty bathroom
Why is your preference for the middle urinal?
I just like the middle one; it's what I choose even if nobody else is around.
It is perfectly normal to have preferences. If you are most comfortable with the middle urinal in a bathroom, then it is fine for you to use than one. As long as you aren't hurting anybody, having preferences is fine.
WTF some people are so judgemental of everything. Why not just let me do what I want?
You might be misunderstanding me. I do think it's you should be able to do whatever you want as long as you aren't hurting anyone.
