re: Parents of the OT, what’s the weirdest interaction you’ve ever had with another parent?

FOUND a kid, he was three or four, at a local playground sitting on a piece of playground equipment all by himself. No one else around. Nearest adults were 200 yards away across a major street at a soccer field. Picked the kid up and was on the phone with the police when a car came speeding up to the curb. Screeched to a halt and a lady jumped out, stormed up to me and snatched the kid out of my arms, jumped back in her car and took off. Didn't say a word to me. Didn't thank me. Nothing. Very weird.
