Very embarrassing moment!!!

Sunday I was hurrying through the Charleston airport to catch my flight back home. It was pretty crouded and I wasn't paying a whole lot of attention to things going on around me. I knew I wanted to stop by the ladies room and pee before I got to my gate so when I saw the sign, I hurried in. I sat down and as I was peeing, I heard MEN'S voices!!! What...I stayed quiet and continued to listen....I looked under the stall and I could see 3 men standing side by side...obviously at urinals....I had gone into the men's bathroom. OMG...what now. I sat there for a while hoping it would clear out but each time someone would leave, another one or two would come in. I had to get out of there. I stood up and braced myself and very calmly opened the door. Two guys were there and they looked at me and then they looked at each other...they smiled at each other and I scattered as quickly as my legs could carry me. I was soooo mortified!! So happy that little episode is over, but looking back on it, I suppose it was funny. I should have calmly looked at them and just said "I'm a transsexual", but I couldn't think that fast. Next time, I will check out the signs more carefully!!
