The other night, Baby attempted what Daddy had already qualified as “bêtise” the week before – pulling the plug from her bathtub, effectively inundating our bathroom.

This time we had a pail underneath, but still Daddy told her in a stern voice “Non!” Since last week I’d broken down laughing, I hurried to add my equally stern “Nein!”
Baby said and did nothing for a moment, then started crying. I don’t know if it was the German or the French or probably just the tone, but she got the message.
(We keep the pail in place anyway.)
