There was one time where I was really angry at my T for having a "secret" session with my Mom. When I came in for my session a week or two after, I gave T a TON of attitude. I'm usually very lighthearted and full of smiles/giggling, but this time I meant business. Instead of telling my T why I was upset with her, I just lashed out at her and said some really abrasive things. I'm pretty sure that crossed her boundary. She's usually very soft spoken and when I lashed out at her, she came right back at me in a very passive aggressive manner.

On a side note, my T doesn't have any children. I'm nosy, curious, and really want to know why. Part of me is curious because she gives out parenting advice. Seriously? How can someone with no parenting experience tell other parents what they should and should not be doing? We've talked about parenting and children multiple times for some odd reason.
Would it be inappropriate to ask her why she doesn't have children? Would that be a boundary violation?
