So, I was in that position.
A guy and a girl met up and somehow broke up right in front of the store I was going into. She got so mad at him,
she gave me all of the stuff she just bought for him but didn't give to him.
Among them, two packs of short neck dress socks and three Adidas sports sweatshirts.
She said, "You can have all of them. Free. Thank you."
I told her she could return them to the store. But she said she didn't care to do that.
Should I have taken her number? I think she wasn't in the mood to give me her number, so I didn't ask for it. I just thanked her for the stuff.
