I am grateful for my sisters. I have two, both are younger. The sister just younger than me married much younger than I did and had children way before I did, so she is someone I have gone to for advice and counsel many times. My younger sister is, and always will be, the baby of the family. She is lots of fun to be around and keeps everyone on track. I regret living so far away from them, but I am glad that my daughter now lives near them and is getting to know them. (And they store her stuff in the summer when she come home!) At some point, I would really like to live closer to them.
Note: I also have a brother who is (much) older than I am :0) who I also love, but he isn't, you know, a sister.
