My friend and this guy in class are always arguing , she generally can't stand each him but always makes remarks when she is near like "i'm starving" he made her mad by taking out some subway and eating it in front of her, he offered her some but she didnt take it. Also today in class had her bag in a chair and he needed it and she made a big deal, they have only known each other two weeks but they are play fighting and arguing like the've know each other for years! what's the deal?
