Wait, what? He's going to go talk to someone about having a bonfire in their own yard? Oh dear. Go get him before he calls the police because the neighbor is (rightfully) ignoring him.
I think my being able to smell it in our totally closed house was too much for him? I don't know. He doesn't love fire pit people when we're in open window season. Apparently he really detests them in closed window season?
I was going to say he is probably having a drink with said neighbours and enjoying the fire, but guess not. I would say grab a glass of wine and go join them and have a great evening with neighbours.
