I'm going to go off on my girlfriend.
Oh my, that sounds very harsh. Why are you going to yell at her?
I don't really remember why. Probably because I was pissed off or something.
If you're mad at your girlfriend, you should talk to her rather than yell at her. Yelling will just make things worse. It's expected that you will work together and communicate with your partner when problems arise in a relationship.
Cool, I'm going to go make her cry.
It is expected that people talk to each other when they are upset if they are in a relationship. You will have better results if you focus on effective communication.
