On Imposing Discipline

It is, I have discovered, quite impossible to Impose Discipline while sitting on the Lavatory. Weeing.
Whilst 'going' this morning noted that Youngest was singing really quite loudly in his room, which would wake up Daughter. Who would be in Foul Mood as she does not like being woken up.
So cleared throat, and called out in what I hoped were Stern Tones.
Singing continued. Louder.
Wriggled bottom on lavatory and shifted feet so as to get more in the Authoratitive Position, and shouted out in a Whispery sort of fashion. Instructing Youngest to Be Quiet Immediately.
The cat, sitting by the basin in the bathroom, got up and left.
Youngest paid no attention at all. And Daughter emerged from room and went downstairs, seemingly unaffected by the singing in the first place.
Sat gloomily on loo, contemplating total lack of control (not bladder, just discipline).
It is Utterly Guaranteed that children will Misbehave when I am Going. Just when they know that I can't physically roar into the room and put an end to whatever nonsense is taking place, they let rip with a totally unsuitable game of Throw the Sofa About, or Let's Run Screaming Through the House. The plaintive calls of their mother from the bowels (pardon the pun) of the downstairs loo has Absolutely No Effect whatsoever.
Alternatively, one of them will be Horribly Hurt and scream the very house down, just at a Peak Moment. As it were. There is a moment of blind panic. Wipe my bottom? Leave it and run to child, with trousers round ankles? Pull up trousers and wipe later? What to do? What THE HELL to do?
So.
In future will restrict mothering skills to when am not attached to lavatory bowl.
Will not mind that Bladder is Bursting. If necessary will use bucket under a very long coat.
Simples.
Mothering. It makes you devious, you know.
And insane.
But you knew that already, eh?
