Heh, thanks for the replies everyone.

I am just joking.

I am sad because that means she is getting older and probably won't want to be as open or talk with her sister as much. Alex and I and one of our brothers (the second Nicholas) have always been super close. So, it's just a super protective thing going on as she is super sensitive but she doesn't really show it. I just don't want her to get hurt. The more and more I think about it, though, I realize that crushes and their ends are a part of life.

I will have a talk with her and just let her know what's up, to be careful, etc.
