A couple of my friends and I a couple days ago when another one of my friends left. We said we would act like none of us knew him when he came back which isn't mean since most of my friends can take a joke.

When he came back we started the prank and he knew what was going on so he was smilying but we were in a mall and everyone around us didn't know and they looked at us like we were being rued and mean to him. even though he was laughing. you should have seen the cold stares i got.
