zoo, you totally deserve your anger about this. You don't have to call again if you don't want to.
I have a confession to make about myself zoo. I am TERRIBLE, I mean absolutely TERRIBLE about returning phone calls. I am probably worse than your T about it. It is because I am a big scatterbrain (some people that work for me have said I'm like a "nutty professor" haha) and just plain forget. Or sometimes I am really anxious about talking on the phone and have to work up the nerve to call someone. Even someone I feel comfortable with. I know it sucks.. I should be better about it

It has absolutely
nothing to do with the other person, and everything to do with my anxiety and forgetfulness.
So, understandable that you are angry! But, you should know, it's not a rejection from T -- it's T messing up, making mistakes.
