one of the dumbest fight i got into started when my BF made a comment about what i had in my trunk because he wanted me to give his friend a ride and his friend had a bag that my BF wanted him to put in the trunk (we were going somewhere in my car, his car was in the shop).
one of the stupidest fights i witnessed was when my friend's bf asked her to remind her teenaged son to clean up after himself. apparent the son would make a sandwich, but would leave the crumbs, the napkin and the mayo covered knife on the counter and never come back to clean it up. she took offense and it went downhill from there
