I had an Aunt like that.
When i was about 8, we used to go camping in large groups.
"Happy Wanderers". Families, that sort of thing.
Anyway, one time, my mom had to leave for a few hours and she
asked my Aunt to watch me. She said, "Sure".
Mom comes back a few hours later.
"Where's Kenny?"
"Oh I dunno", my Aunt lovingly replied, "Not my kid."
Last time Mom asked her to keep an eye on me. tongue emoticon
