I'm going to tell my friend she was being childish
What did your friend do that was childish?
She said something that was pretty messed up according to what i believe.
Your friends behavior must have really upset you. Go ahead and tell her how her behavior made you feel, but be sure to be kind while having the conversation. Otherwise, she could be very offended.
I will not hold back on this. I'm going to make a scene. This is not okay.
Well it is great to be honest and upfront about your feelings. There is really no need to address this situation out in the open though just to make a scene. This would be a childish act as well.
