Yet another embarassing moment

One Tuesday afternoon, ok, it was yesterday.... while trying to pass the time and get myself in a mathy mood, I decided to listen to my awesome Confessions of a Shopaholic soundtrack on my MP3 while walking to class. I decided to head straight into the women's room before class started. I was all alone, and I noticed someone walking in while I was doing my business, but didn't pay much heed to it. I washed my hands and proceeded to check my face out from all three angles huge mirror with three panels. I guess the fact that I didn't see and couldn't hear anyone gave me the peace that I was alone, so I did my little JLo head bob to the towel dispenser, I saw the girl walking straight toward my neighboring sink through the mirror. Oh, the horror!!!! I don't think I have ever been so embarassed! She was nice about it, she just laughed and laughed and said "You're fine!" Oh my life....I have had my share of embarassing moments, but this-I don't know if I will recover from this.
