A Good-bye

Something hit  me the other day -- not anything physical, but a thought.
All my life I've said I didn't want to wait until I was 30 to have kids like my mom did. I'm the oldest of three. She was 35 before she had my brother.
And until now, I had a chance to achieve that goal.
I will be 30 in August. August 28, actually.
Unless something happens and I get pregnant in the next month and then have a preemie, I won't have a child until I'm at least 30.
So, we say good-bye to this promise I made to myself forever ago. I know it's silly to think so seriously about something like that. Everyone says I'm young, and I know it's true. But, still. . . it's sad to me.
