Story two: 100% the A-hole, nothing about it was inappropriate! She threw it away and wasn't visible, she could've flushed it down the toilet like some other idiot girl did which ruined the toilet. And getting in her face is uncalled for, it makes me wonder how he'll react if he was in a relationship with a girl and she threw her pad away in the trash can in the bathroom, would he be mad? Or would he not care or it could just be since they don't have a good relationship he's bringing it up. Plus I wouldn't want to have to carry my pad just to throw it outside in the trash can, there's a trash can in the bathroom for a reason!
The story honestly confuses and makes me mad at the same time, and I would agree with you. I fail to see how it's inappropriate at least she put it in the trashcan and plus it would be disgusting having to bring it with you just to throw it away
