I usually just lie and say that I don't have the opportunity to work with them that often. I only work 2 days a week, and it's a big hospital with lots of docs, so I can usually talk them into believing that.
What I hate more is when there are huge family get togethers, and some family member of an in-law asks questions totally unrelated to OB. As if we all keep a wide scope of practice and knowledge in every possible subspecialty.
"Oh Heather! You'll know! What cardiologists are in the NW Ohio Cardiologists practice?"
To which I reply "I dunno. I don't believe they have delivered any babies lately?"
I became the outcast at a recent function when I was being hounded by one woman. I finally told her that unless she needed help breastfeeding or wanted me to check her episiotomy, I would appreciate it if she would leave me alone.
