Doesnt take a lot to confuse them, bless them
That same kiddy then went to the next level of "clear lights" lol, no red reflectors, they also got a bit confused over his turbo timer after they asked him to turn the car off and he replied "well the keys are in my hand"
He does like to wind them up though, after that little incident he went and found the smallest red reflectors he could, just bigger than a 5p, they didnt find it as funny as we did
