When were you happiest?
On holiday with my friends 1, 3 and 5
What is your greatest fear?
Being divided by 10. The idea of being one and a half again frightens me.
What is the best sum you've ever been involved in?
Well, it has to be the square root of 225. I was the product.
What don't you like about yourself?
I hate the fact that my unit's digit is a prime.
What makes you depressed?
Knowing I'll always be an odd number.
