Did you know that I tried to protect my mother from her abusive boyfriend when I was a child?
That's really nice of you, how did you protect her?
I stood up to him and threatened him when he started to hit my mother.
Protecting a family member is a great thing to do. It sounds like you cared for your mother very much. Taking that type of responsibility is wonderful.
I'm just happy that everything worked out well and he's gone.
I'm sure your mother was very grateful for your help. Protecting her from abuse could have been very dangerous for you, but you put the needs of others first.
