In the laundry room:
Adam: Mom is cleaning.
Jim: Yep, Mom is cleaning.
Adam: She's cleaning dishes?
Jim: Uh...nooo....she's cleaning laundry.
Adam: Mom are you cleaning laundry?
Me: Yes. I'm cleaning diapers.
Adam: You're cleaning diapers, and underwear?
Me: Yes, Adam, I'm cleaning diapers and underwear. Your underwear.
Adam (giggling): Mom's cleaning my underwear. (emphatically): Mom, thank-you for cleaning my underwear.
Me: You're welcome, Adam, happy to do it.
Aren't three-year-olds sweet?
