Mama's Helper?

I sort laundry into piles,
by size, not by color.
Our clothes are now blue-gray,
the shade of denim, only duller.

I help around the house,
Mom likes it, too.
Except when she doesn't -
like when I dye the laundry blue.

Now when I offer to help Mom,
she gives her head a shake.
"I've got the laundry covered,
go help your Daddy rake."
