Me: What took you so long?
Beta: I had to put my shoes on.
Me: Well, Gamma left without you.
Beta: (sounds of outrage and distress)
Me: You’ve been mean and rude to her all morning, she’s convinced you don’t like her, and now you’re going to be upset that she walked to school without you?
Beta: (Distress intensifies as he fights with his jacket)
Me: What did you think would happen? No one is going to waste time trying to be friends with someone who’s mean to them. And now you’re on your own. Have a nice day at school.
