Helpful boy

I'm trying to be helpful by collecting things from around the house and bringing them to Mama. She usually thinks it's nice (I know she needed that tea kettle while she was folding laundry, and who wouldn't want my socks and one of Daddy's sneakers?). But for some reason she doesn't seem too happy when I pull the outlet covers and corner guards off and bring them to her. Something about "baby-proofing" not working so well for toddlers. I have no idea what she's talking about.
