I behaved myself under a direct threat to "behave myself" from my Mom, step Dad and step brother.

So I went in (after a very long, detailed, somewhat heated conversation with my Mother on butting out), was completely sociable, polite, etc, until... his repeated interrupting a conversation Mom and I were having, because he felt that his need to be "served properly" (in my Mother's home) was more important that any conversation we could possibly be having. And that if I wanted to have a successful relationship with a man, that I should curb my tongue and "snap to it".

This was AFTER having butted into a conversation I was having (in another room) with my brother about my current job that I'm having difficulties with. He stated that he firmly believes that a woman's place is at home and not "playing around and mucking up" the workforce with sentiment and maternity leave. And that his future wife will know her place in the home as the mother of his children and the keeper of HIS home.

Heh... he's still alive only because I didn't want to shed blood in front of the kiddos that were present. Although, it was suggested that they go outside and play just before I verbally filleted the jacka$$.

I honestly at first thought the guy was joking. It was that over the top. Thankfully, my step Dad was laying down when the worst of it came down because he has a very bad heart and should not be upset, so he didn't have to deal with him. I think he might have shot the guy on the spot if he had been awake.

All in all, I think Mom has learned her lesson.
