Most Embarrassing Moment

When playing the get to know you games that seem to come standard with all new groups that I joined in college, one of the questions was always "What is your most embarrassing moment?" I never really get embarrassed, but to be a good sport I would tell a story about a time I was trying to be a gentleman and pull out the chair for a girl at prom only she didn't know what was what I was doing. Thus, when she went to fluff her prom dress underneath her, with no intention of standing up, I pulled her chair out from under her and she hit the floor with a thud. That was my default answer.
I was thinking about this the other day, when was the last time I got really embarrassed? And a memory came to mind. I drove buses for the Texas A&M transportation department for most of my college career. Absolutely the best job you can have in college. One morning I was behind schedule and had a full bus. I pulled up to my last stop and had standing room only. As the last passenger squeezed in the aisle and I was about to close the door, I looked and saw a girl across the street trying to signal for me to wait for her. She was dressed for what I assumed were interviews and had her arms full of books and file folders. I motioned to her that I would wait, much to the chagrin of full bus. As we all looked to our damsel in distress and waited for her to make it across the street, the heel on her high heels stuck in the wet grass and she face planted on the sidewalk. Fortunately, her books and papers broke her fall a little. Unfortunately they flew everywhere. With one of the saddest faces I have ever seen she looked up at a jam packed bus that had all just seen her bite it, and motioned ever so slowly for me to go on ahead without her.
That wasn't my most embarrassing moment, but it was the moment with the most embarrassment that I have ever been a part of. Ouch.
