jitkaau, we've been doing that for years! "Smile and nod". Or more like "Smirk and shake" the head.
I didn't explain that she does not live in the property across the road, tho she owns it. She lives way down the road! She's not really a problem normally but can be like this. Been trying to sell the property for years but something about going through a nasty divorce means neither has clear ownership and taxes have not been paid for at least 12 yrs!
Anyway, I truly pity her.
