Growing up and growing apart

Bodhi got his nails done today. Once again he got complements on what a handsome boy he is. People always seem surprised when they say it too. He is really handsome! Bodhi the haflinger ambassador! I am such proud mother.
After he got his hooves trimmed we went on a leisurely stroll through the back pasture. It was nice. We are both learning to relax finally. I got to do some thinking and I realized I am moving Bodhi to a new farm for more than just the convenience factor.
The girl who resides at his current digs is my best friend since the 6th grade. She has always been a little hard to connect with and unreliable. She has been that way since we were kids. Well I suppose now that I am transitioning into adulthood I expect her to evolve yet she stays the same static charcter. Things have been exacerbated by the fact that she is the partial caretaker of my precious Bodhi. I used to almost look up to her flippant nonchalant personality but now it drives me crazy. How can she be the same age as me and be ok with where she is? How can she treat people the way she does? It tears me apart.

I guess what I wondering is if moving Bodhi will be the end of it or if I will also move on from our friendship. She has never been the kind to call or make plans, or really put much effort at all into our relationship. I think it will pretty much die if I stop putting in the effort to stay connected. I am torn about it. But I think it may be time to back off and let the chips fall where they may. Is this what it is like to grow up? Realizations not only about yourself but also the ones you used to hold essential?
