My aunt adopted a severely handicapped little boy and kept him for many years until he succumbed to his condition; she first took him to her sister’s house for a visit when he was stiil about seven or so.
She introduced him to her brother-in-law as Kevin and informed Kevin that everybody called her BIL, “Uncle Lee.”
From that day forward, Kevin, my aunt and all who knew them would greet my uncle the same way Kevin did that first day: “Unga Lee, Unga Lee” and give him a big hug just as little Kevin did.
That’s a nice story. :)
