PRETTY GIRLS, STUPID THINGS

So I said, "Excuse me, did you know your shirt was on inside out?" And the person, who was May, turned around and said, "Yes I know that." When she turned I could not help noticing that she was unfortunately very pretty. I hadn't seen that this was a pretty girl, here, or else I almost certainly wouldn't have said anything whatsoever. I have always tried to avoid talking to pretty girls, because pretty girls have a vicious effect on me in which every part of my brain is shut down except for the part that says unbelievably stupid things and the part that is aware that I'm saying unbelievably stupid things.
