You and Stan have been friends for a long time, although no one else knew about you because who cares about it? Maybe Kenny knows but almost nobody understands him. You and Stan only saw each other during the summer holidays because you came to visit your grandparents, you could say that you and Stan were long distance. Also your parents and Stan's were friends When summer vacation came, you came to visit your grandparents as usual and spend time with Stan, although he started to reject making plans with his friends to spend time with you.
Kyle and Cartman began to suspect and theorize about why Stan no longer wants to hang out with them,I mean, sometimes Stan doesn't want to, but it's rare that he refuses to play or hang out for several days... Rather, Kyle started doing it, Cartman just said nonsense shit as if it were a shitty Hollywood movie. Kyle started asking the others in the class if they had seen Stan or if Stan had hung out with any of them, most of the answers were "No." Except Cartman, who said that maybe he run away because some Jewish mobsters wanted to kill him or some shit like that On Saturday afternoon, Kyle invited Stan to play wizards, paladins, etc. (whatever, too lazy to look up the name of the game) with the others, but Stan said no. That same afternoon, while playing, they saw Stan in the yard of your grandparents' house, your dad had bought you guys ice cream your dad: "Here you go, kids. Enjoy yourselves and don't spend too much time in the sun. I'll be cleaning the pool in the backyard. I'll let you know when the pool ready." Your dad ruffles your and Stan's hair before leaving
