Many years ago when our son was 8 or 9 he and DH got some sort of kit and needed to have really small nails to hold parts while drying.
What do you think they found that would be "perfect" Took my brand new expensive scissors and cut the head of my pins. I was sooo mad I dared not speak a word. But later DH got an ear full which was pasted onto our son. They never touched anything of mine again without asking.
