I volunteer for my kids' schools and PTO, I have a rescue dog and two rescue cats, and participate in Relay for Life and Livestrong events every summer. I would rather be "making memories" for my children than doing almost anything else.
People often make judgments on first glance and have to be convinced otherwise by interacting with the person a while. And some people don't even interact, so changing their mind isn't even an option. That's sad.
