Hmmm what's the most embarrassing thing you've done so far in life? Well, that you feel comfortable sharing.
Well, there are far too many to rank one as "the most," and some I would not dare tell hardly a soul! But, here is one of the more tame, but still highly embarrassing at the time (others are actually still embarrassing for me when I even just think about them, even if it's been years).
When I was in high school, our entire English class plus another class or two went to the library for some reason that I cannot recall. Everybody was to have a seat in a sea of chairs that formed some sort of audience, as though we were going to be read to or something. There were not quite enough chairs, so I went to the back of the room and grabbed one, and started pushing it alongside the group and decided to push it as quickly as I could, sliding it along the carpet while I ran(?) behind it. I was now pushing it behind some cubicle reading areas where the top half of my body was visible to the group of students on the other side. I was alongside the group, pushing as fast as I could (for some unknown reason?), when the chair caught some part of the carpet and stopped dead in its tracks, sending me flying over it. It was a giant sound, I hurt my shin, and from their view they would have seen the top half of my body scurrying along, then I just suddenly disappeared with a very large thud, and the entire room of people saw what happened. I did not want to get up and wanted to stay hiding behind the partitions. Can't recall what happened after that!
