Embarassing? Ha that's my life right there! But no worries, I'm a fail-master. You just got to roll with the punches and not let it bother you. I was a ditz with a ton of friends. However make sure you aren't a push over, if someone crosses the line make sure you put em' in a choke hold!
Hmmm well for the most part if you don't make a big deal about it and don't really react to it then you'll be fine. In other words if people around you see it didn't bother you then they are less likely to keep bringing the incident up. If you can laugh at it yourself all the better.
ha i remember we were supposed to be going off into groups so we had to count to 8 or something, and i miscounted and got laughed at. i was already stressed from a bunch of other stuff going on so i broke down. stupid really. another time in marching band during practice when we were learning a new routine, my friend and i were talking so we didn't hear where we were supposed to go. so we just stood there when everyone started to move, and got told off by the director. everyone laughed then too, and we just laughed with them.
