I have 6 sons of various ages. I want to know why boys don't know how to:

Flush a toliet
Hang up a wet towel
Slide a chair under a table
Put dirty dishes in the sink
Get dirty socks in the hamper
Put a cap on a marker

I also would like to know why they leave 5 pieces of cereal in a box, two drops of juice in a bottle and no gas in the tank of any vehicle.
