"Come along Sylvia, time to put on your diaper." I herd one small, three year old, step-sister-in-law to bed.

"That's not a diaper, that's a nappy!" She crows, demonstrating how she knows the proper names for things and her adult babysitter does not. Next she teases me for calling her dressing gown a housecoat.

Mum, forgive me for ever teasing you about your slight Texan accent. You can call Washington state, Worshington, any time you like.
