He did it just for fun. He thought she would find it funny. She would come at around 9 pm, as usual. She would knock at his door and he would open it. She would laugh out loud for at least half an hour. They would fuck all night, still laughing about the thing.
But she came a little earlier. She was nervous, she didn’t even see the thing. She left him. She didn’t want to be in this relationship anymore. He felt like a loser. Twice a loser because of the thing he had created on his face to make her laugh. You can’t be sad and have a funny mustache. It’s kind of awkward.
