Turning Gray

Yes, it is true, I found a gray hair on my head of brown. This shouldn't come as a surprise, my sister (love ya) has had gray hairs since she was in her early twenties (or late teens?). I have had 3 kids in 4 years and 2 of them are red heads (yes, pretty much everything you hear about tempers, and attitudes are true with mine). I am 25 you know, and that means I am no longer closer to 20, I am on the downside of 30 (ugh!).
I have not died my hair since college. It was only once and my roomie Andrea colored it for me. It wasn't even that different of a color, it was a red and no one could really tell that it was different. I did have some highlights in high school when they were cool, you know, they were really blond highlights with my permed hair (all the rage :) haha) oh, if you want to see them, go here to my friend Kelie's blog, she wished me a happy birthday with my senior picture :).
My mom always told me if you pull a gray hair out, 10 more will grow in it's place, so I left it in. Now, my question is, when I get more, do I dye my hair? Do I put highlights in? I don't even know how long my extended family ladies (you know who you are) have been coloring their hair, I know it is a long time. I am sure it is spendy, and I know this is a little bit of an over-reaction but I just want to be prepared for when the day comes, I look in the mirror, and I have to do something :)!!
Wow, I know this is a random post, but it is a big day, the day no one wants to happen. The day when time shows up on your head! Well, I am off to look at it again, and decided if I am going to pull it out!
And P.S. I have a winner for my challenge that I posted awhile back, but the project is taking longer than I thought, so when it is finished (this week) I will be sure to let that person know. I just didn't want anyone to think I forgot!!
