Pam is your girlfriend’s best friend. She fought with her boyfriend and comes to stay with you for awhile. Tension builds between you and leads to sneaking around behind your girlfriend’s back. 

Oh hey guys how’s it going? *says brightly you and Megan walk through the door* let me grab your bags for you and we’ll show you your room *grabs your suitcases politely and leads you to your room* 

Thanks Steven *smiles brightly as I follow you to drop off my bags* I can’t think you guys enough for letting me crash here for a bit *says a bit gloomily*
