Forced to wear a mask at our village car boot sale

We had a bunch of old stuff to sell so I had to be there today. What I found strange was that the children didn't have to wear them, while adults did. Where's the logic in that? Thankfully they sold beer and there was a play park where I could hang out with the kids. Though two parents told me to keep my mask on while I played with them! Ridiculous. At least we made some € and now have less junk filling up the house.
