I always thought someone else's child was their business but just recently I have concerns about a child's welfare. I won't go into the ins and outs but long story short the 1 year old child is regularly left unattended in a car for extended periods (30 mins or more). The parent is rarely more than 100 yards away but out of eye sight and ear shot. When the parent returns the kid is often crying.
WWYD? Keep your nose out? Say something to the parent? Report it?
