Interpretations — of the other person's behavior. Think about possible reasons why she did the thing that upset you. Start with outlandish reasons (to open your mind) and move toward more realistic reasons.

"She was raised in a lab and doesn't have a heart → She wasn't raised in the lab, but she works for the lab and is doing tests on how mean she can be and get away with it → Her hamster died this morning and she's masking her sadness with meanness → She struggles with depression and just had a snap that caused her to be rude → She's just human and got frustrated and didn't manage it well. We all make mistakes."
