Don’t check your girlfriend’s phone when she’s in the other room, you coward. Who cares if she’s talking to other guys? If anything, you should be checking the toilet when she’s in the other room. If she has cool turds, she’s a keeper. If she’s a keeper, you should be concerning yourself with treating her like the living angel that she is so maybe she’ll stick around for a little while longer and continue to let you bathe in her indescribable beauty and benevolence.
