This may be totally stupid, but I have a hostile reaction when people say, “Oh, you’re driving around in an RV. Cool. My grandmother does that.”
This usually happens after I’ve told them of our totally awesome, unconventional, fearless life on the road. After I’ve specifically told them that I live in a big camper van. (Which, OK, technically is an RV but, in my world, is my free-spirit house on wheels.)
