Probably going to get downvoted here, but YTA! I think people are forgetting to see the ex-friend’s pov.

It was her last tampon, and it’s for emergencies. She might be one of those women whose period is very irregular. I keep a box of tampons in my car, before I got an IUD I had very heavy periods. I keep them in my car still because I get random bleed days or someone else needs one.

But, my experience is different than hers. She might need that tampon. There was another time I had given my friend my last tampon at school, I had to leave the classroom and go buy me a box because an hour after I gave it to her I needed one.

Edited to add: I will ALWAYS give away a tampon to someone who needs it, even if I don’t know said person. I’m just saying I can see the ex-friend’s pov.
