When I was 15, my beautiful, wonderful "little sister" picked me at church. I had just joined, I had begun helping out with Sunday School/Children's Church and she was just 5 at the time.
I have no idea why she picked me, but she was quite determined about it and I couldn't be more grateful. She plopped herself down in my lap one day and that was that.
I babysat for her several times, she invited herself along when my friends and I went to the pool (as 16 year old pretty good kids, we thought it was kind of funny to have a little mascot) and we were just very close. We had breakfast, I went to her school events, we went shopping, and we stayed connected over the years. I took her to Disney twice.
Things of course changed as she grew up. As her life got fuller, I faded to the background which is normal and natural. We still care about each other and she knows I'm always in her corner, even though she obviously doesn't have the free time she had when she was 10.
She's now off to college and about to turn 20. We stay connected via Facebook and I try to see her when she gets home. I'm hoping to go out there to visit her.
I guess it is unconventional, but you can't really control who you connect with. I also had friends my own age and normal teenage stuff like boys, jobs, and college.
She has been such a delight to watch grow up over the years and I enjoyed getting to experience the "kid" stuff I was technically too old for. Kids are fun.
For her, I think I provided some one-on-one attention, which was hard to get at home with an older brother, surprise baby brother, and overextended parents. I was someone she could talk to who could offer a more mature perspective when talking to her parents was hard during the teenage years. Plus we had tons of fun going to the mall, the pool, bowling, Disney Quest, WDW, and all sorts of other fun stuff!
As for what happens now, she continues growing up, I keep living my life and we stay connected. I can't wait to watch her graduate from college, pick out her wedding present, and dote on her children.
As a parent, I would of course proceed with caution, but it's been wonderful for both of us and I hope other kids can find mentors and friends. Kids can use all the love and support they can get!!!
