I'm the only punching bag...actually I haven't gotten in any fights outside my family. The last one was about 8 years ago and my sister and I were half-fighting, not seriously, until she grabbed my chest (female equivalent of going for the balls) so I smacked her across the face and left a welt.
Actually now that I'm thinking of it, I did hit someone back in 10th grade. I was at a swim meet, I barely even knew the guy (he was a freshman from a different school) and he grabbed my ass. I told him, "Just wait, I'll get you." And then a week later I saw him at the pool and slapped him on the cheek, he had a handprint for a few hours.
Oh, and then in 10th grade, some guy kissed me on a swim trip, (he was so bad I thought I was gay!!) and found out the next day he had a girlfriend. I ran into him at the swimming pool, he was straddling a stair railing talking to some guys and I pushed him down the stairs. He was scrambling fast to keep his hands under him, but no injuries. We ended up somewhat of friends later.
I know, if I was a guy I probably would've and should've gotten my ass kicked. I doubt I could defend myself in a real fight. You know how the movie cliche is that in a panic situation, everything goes into slow motion??? Not with me. Everything speeds up and I just get dizzy and confused. I'm worthless in emergencies.
