My experience,...my thinking was twisted till well into the amends process.
Slowly it dawned on me, that everyone wasn't out to get me or **** me off.
My attitude to life and people in it began to change....looking back i see how at odds with the world i was.
That said....its fair and reasonable for you to to ask for some privacy, ..but i wonder how angry you are?....is this a case of your sponsor feeling intimated.?
Maybe that's why she wants it in a public place ?
Most important ....see this through .....if your like me, you will slowly start not to recognize the old you, peace will start to filter in between your ears...then god willing, your be approached by someone just like you was...looking for answers and solutions.
