so I said "Oh you mean like when I say TY and never get a ur welcome" she said "whatever" realizing I just got her upset, I changed the subject and went back to being upbeat...
this is it in a nutshell. This is what you are supposed to avoid. I suggested days ago that you be upfront and tell her matter of fact that you like her to be civil to you and say thank you, hello and goodbye. You didn't do that. You did this instead. This is bad because it is underhanded. It is a jab at her. It is mean. Yu could have told her in a neutral way, but instead you chose to jab at her and accuse her of being rude to you.
