While not a weird or odd name, like athersgeo, I too have a common name. (Christina) well, growing up I knew two others with my name. Kristina and Khristina respectively. Well we all got shoved into the same eighth grade math class together. Our poor teacher! It got to the point when he said 'Christina' I didn't know who he was talking to. One time he stood in front of my desk and shouted my name three times before I responded.
Then again, this was math class, so I curled into a tiny ball trying to look as small as possible so he didn't see me, hoping that when he said Christina the other two with my name would pick up the slack. It failed... miserably.
