Sbaglio I feel for you as I am the same way. Why do I grasp for answers when a total stranger asks a personal question?
My DD is at an age (6) that she talks about her first family as if she knows them and will tell almost anyone who will listen about her brother and sister. My DBfriend has no problem telling noisy people their question crosses the line but me, I fumble and stumble. Please let me know when you have answers in your hip pocket ready to pull out at a moment's notice because I need some help too.
