He’s cheating on his girlfriend right in front of her
Here’s the scenario: a guy kissing a girl at the bottom of the picture, and the lady watching them is his girlfriend. Two of them are having a wonderful time, but one isn’t. Can you tell who it is? Come on; it’s easy.
We can almost hear this image, “Hey, put me down!” At least if she comes down from her boyfriend’s arms, she’ll be able to find her own hookup for the night. Maybe she’ll even make him watch.
