Interesting observation

While out the other night I came to an interesting (or at least I thought it) conclusion. In men's washrooms there are generally urinals and stalls. Using the urinals is obviously common place and they are out in the open with little to no privacy. This is normal. Strangely enough though, when a man uses the stall to pee and doesn't shut the door, it somehow seems as if you are intruding on him is the door is open. Really, this chap is afforded more privacy then anyone, yet it seems that he is the most exposed. Bizarre.
