Accidental nudity..

First off I live with my husband and his family (mainly his grandpa whom we take care of but his mom and brother visit) So, normally I'm awake before anyone else in the house so I just walk from our room to the bathroom either naked or without pants. But this morning without even checking I walk out butt naked past his 75 year old grandfather and whilst walking back to the room red faced and trying to cover up everything he says "you have nice pussy hair, if I gave you $40 would you give me a hug?" I'm now mortified and I can't tell if he was joking around or was being serious... I feel like we should just move out...
