Or, more specifically, a suitable person to look after a child. I ask because tomorrow my suitability is to be judged. And by a 19-year-old boy. Okay, I exaggerate: he's probably in his twenties.
If they were to ask my grandchildren if I were a suitable person to look after them I know what their reply would be.
But is the ability - and willingness - to sing, 'zoom, zoom, zoom, we're going to the moon', 83 times non-stop enough?
We shall see tomorrow. I've made a special effort and cleaned today but I don't think George would appreciate being deodorised. We shall have to be on our best behaviour and I must try not to say anything stupid.
Talking about stupid things have I told you about the latest fitness trend that has affected our circuit training sessions? It's called tabata and it's acclaimed as a fat-burning miracle - to which my fat seems immune.
Look it up on the internet and you'll find it associated with phrases like superfast, high intensity, fast and furious, bootcamp style. Got the picture? Jules, our trainer, introduced it to our sessions a good while ago now and he fits 3 tabata 4-minute extras in between our circuit stations proper.
If you fancy trying it here's one of my least favourite groupings.
So you're going to work as hard as you can for 4 minutes. There are 2 different exercises in this: squats and 'lie downs'. When you're squatting make sure your weight is on your heels and that your knees don't go in front of your ankles, and squat deeply. Do that 10 times.
Then stand up before lying down so that either your chest or your shoulder-blades touch the floor and then stand up straight again. Do that 10 times.
Keep on alternating between 10 squats and 10 'lie-downs' for 4 minutes - or until you can't push yourself any more.
You think it doesn't sound too bad? Lying down must be nice. You'd be right and wrong. Lying down is fine; it's the getting up that finishes me. You wouldn't believe how long 4 minutes can be.
After having to do that twice last week I'm really really hoping we're not going to have to do it tonight.
