Prime Numbers

I was talking to my cousin recently. She is very intelligent and married to a man who also is very smart. She told me that he chose their phone number because it is a prime number. I told her when we get a new phone number, I'll be sure to ask for a prime number and if we don't get to choose, than we'll have to settle for an even number. Then, she kindly taught me that a prime number is a number that can't be divided evenly.

You see, it's not my fault. I don't know what an adverb is either. I have an explanation for it, but it may only make sense to a woman that has numerous children.
