Yeah, ya gotta be careful what you tell the younguns; especially if momma can get at ya! Some mommas just don't have a sense of humor.
I don't remember when I learned the difference in smell between my Levis and virtually anything else. I was young though, under 9-10.
Dad had me holding torch for him by then and he just let me discover the importance of keeping the smells straight. Mother didn't brain him for letting me get burned either, heck, SHE thought it was a good idea. I don't know how many times she told me, "You'll know better next time won't you?"
I always wondered about kids who's mothers didn't laugh at them when they did something dumb and got hurt. Another favorite Mother saying was, "If you hurt yourself I'll paddle your butt when we get back from the doctor!"
Attached is a pic of Father spinning hot. Sherrie is holding the torch for him, she was Dad's business partner's wife. Anyway, I was young enough I had to stand on a bucket when I started holding torch for him.
