One day in high school, I got my period. Since I had to stay after school that day until ~6, I reeeeally wanted a change of underwear. I also needed some motrin because the cramps were awful. So, during my lunch period, I ventured out to the kmart across the street and picked up a new pair of undergarments. When I was checking out, I happened to note my crush checking out at the register behind me. Cue IMMEDIATE HEAD SWIVEL IN THE OTHER DIRECTION. When I finished paying, I heard him start to call a greeting, but, panties in hand, I WAS ALREADY FLEEING AROUND THE PERIMETER OF THE STORE. I vanished into the bathroom, changed, then sat there for the rest of lunch. Dreading leaving. When I saw him after school, he said nothing about the incident, so to this day, I have no idea what the hell he thought I was doing. I just hope it was anything but the truth.
