Favorite stall?

At my job, I've developed a favorite stall. I don't know why it's my favorite, I just like it. Maybe it's the fact that it's one of few stalls that lock (actually, that's definitely one of the reasons). Maybe it's because the stall is generally clean. Maybe it's because the graffiti is interesting ( on a side note - who walks around with Sharpies in their pockets so they can do public restroom graffiti? I think that's a strange behavior... ).

It's like an old friend, that I can count on each day.
