That's basically it: AIBU to tell my H that I don't want him to take BOTH his hands off the wheel when driving, in any circumstances, but in this case to eat the remnants of his slushy with the stroon/spaw (whatever a straw with a spoony bit on the end is called).
This is how it went down:
DH took both hands off wheel to scoop slushy remnants.
I put my hand on the wheel and asked him not to and took the slushy to hold for him.
He took both hands off the wheel to demonstrate that he didn't need to hold it.
I told him to stop being so irresponsible with our two DC in the back of the car - anything could happen in a split second.
He continued driving for 5 minutes, slushy melted, I passed it back for him to drink.
'D'H took his hands off the wheel again to scoop up slush.
I made him pull over (he didn't want to) so that I could drive.
AIBU to think he was being/is a total knobhead and completely irresponsible and doesn't respect me?
