Scene: A tired but happy scientist/mother picking up her toddler from pre-school. Mother enters stage right. Teacher is reading books to children. When scientist/mother enters, teacher stops reading to greet her.
Bean Teacher: Lately Bean has been wearing shirts. Do you still have onesies for her?
ScienceMama: Yes, a few.
Bean Teacher: Would you mind putting Bean in onesies for a little while? She's been tugging at her diapers lately.
ScienceMama: Oh yes, she's been doing that at home sometimes too. We've been trying to teach her that her diapers are dirty.
Bean Teacher: Today she stuck her hand into the back and got poop on her hand...
ScienceMama: [Mortified silence]
Bean Teacher: ... and then wiped it on another child's mother.
