I'm going to call my flakey friend out while she is having a bad day.
Do you ever consider her feelings?
Feelings are just there to manipulate others, and I won't let her do that to me.
Your friend having a bad day doesn't seem to bother you as far as empathy goes. Her friendship should mean more to you than this, act like a real friend and be there for her. She will think you are a fake and then dump you, and you will deserve it because you are so mean spirited.
I will still call her out. She is going to be shocked and heart broken. I'm going to make her feel hurt.
Come on, that's not the right thing to do. Why are you friends with someone you want to be mean to?
