Do you?

F.r.i.e.n.d.s has this episode where someone (who was it?) confesses to always closing the bathroom door even when there's no one in the house.

 

Was this weird? I do it most of the time. I tried departing from the usual practice today and the exercise was kind of uneasy. I almost grew paranoid of someone wandering in and inadvertently invading my privacy. I was particularly harsh on myself trying to recall if I had indeed shut the front door.
