When your best friend is pregnant and you realize you won't have kids at the same time as planned. In fact, at your rate hers will babysit yours. - I don't compete with my friends. I think this idea is really cool if I should have kids.
I was not, am not and never will be a runner even though I can picture a young, thin me in a really cute running outfit, ipod plugged into my ears and long ponytail swinging from side to side. Alas, I am not a runner.
