Sounds like you better collect a few more irons or give him one on his next birthday.
I'd be happy if my son even knew HOW to use one. Or DH for that matter! I tried to teach them but I think they pretend they can't just so I will do the ironing for them. (DH admitted once to that effect)
Bet your son will be trying to make up to you for Mother's Day.....hmmmm...might be a good oportunity there for you :lol:
