this is an old one, but still holds true

Do not wash your 6 year old's clothing with his dad's dress shirts unless you are willing to stick your hands in their little pockets and pull out all the crayon pieces.

Men's dress shirts with vague colorful scribble crayon designs are useless and
the stains do not come out.

Can anyone guess why my sons learned to do their own laundry when they were still little?
