Matthew: I can't get this fixed! (referring to the corner of his sheet that is not on his bed.)
Me: You have to get off the bed to do it.
Matthew: Will you help me do it? (He's just laying on his bed.)
Me: You want me to do it. (letting him know I knew he wouldn't be helping.)
Matthew: Sure! Thanks for offering.
Right now he's in bed, serenading us with his recorder. He plays a mean Mary Had a Little Lamb.
