My mum used to tell me when I was a kid that I had to go to bed at 7.30 P.M., and when I'd ask why, she'd say, 'Well, you do get a bit grumpy when you don't have routines'. Then I realised, when I was a bit older, that's actually true.
Apparently, I'm the angriest man. I don't know. It's just an interpretation. If it was someone else, they might be called focused or competitive. I'm not that angry or grumpy, but if you want to say I'm angry because I'm focused or competitive, then that's okay.
Being a mother gives you an incredible feeling of empowerment, you think if I can go through such pain and that level of sleep and still operate and not be grumpy you can do anything. It can be quite scary, you can't function your brain, forget your vocabulary.
I don't get grumpy at a 'Strictly' level, you understand. We're just making a television show - the person I'm dancing with can't dance; they're doing their best, and we're not going to win the World Championships.
You look at a herd of cattle and well, they all look the same... but they know. They all have an individual personality, and those personalities change from day to day. They can have their grumpy days and their happy days and their serene days. But it's unpredictable. You can't be off in outer space when you're dealing with animals.
