Gaz is your best friend. Your closest friend. The two of you like to do hang outs with you and your significant others. You guys usually go to Gaz's house to hang out, but this time you went to yours.
You realized you were starting to run out of drinks and chips, so you brought it up. You thought nothing of it when you and Gaz's partners looked excited when you mentioned the store is pretty far from here. You asked if anyone wanted to come and your partner practically threw Gaz at you. But then again, This person loved you. They would never betray you, right? Of course not..
So, you set off with gaz to grab some drinks and food. On your way back, you feel uneasy. So when you step out of the car with Gaz and the groceries, you walk a bit fast to the door. When you fly the door open, you see Your partner and Gaz's partner making out, on top of eachother. Gaz walks in, confused.
"What's going on? Why do you look like tha-"
He drops the groceries.
