Hmmm, if they are saying it to be b$tchy , I would prob just smile and gulp my wine !! If they were just innocently asking , I would explain .
I usually get a lot of sympathy because my mom , auntie, and their friends all "babysat" in their day !! So they understand !!! The younger ones are easily impressed by how I talk about my business and the rude ones I don't care to discuss myself with .
