It was a moment of weakness I'm sure I'll regret for a long time to come.

There aren't too many spells, per se. Most of it's utter bollocks about discipline that I remember quite vividly.

But one or two of them do sound horrifyingly familiar. (They also fit with what the portrait said - shrieked - about my failings coming home to roost.) The 'Discretion Charm' is underlined; description says it's to 'keep little mouths closed from embarrassing the family!'

In the entry on 'Impulse Control Charms' there's a short section on side effects. Mother wrote in the margin on a few of them ('R' and 'S'). I can only assume that means we exhibited those symptoms.

Do you really think this is the answer?
