You can never go home again

OK, so you can, that just doesn't mean it will be the same. The strangeness of being back home is sinking in. I was fine until tonight. I spent the last two days hanging out with my two best friends and everything was fine. But tonight I went out with two of my close girl friends from high school, we'l call them Rose and Kelly, Rose had been my best friend through high school. It was just...uncomfortable. Especially with Rose. I just didn't feel right around her. Maybe it's because our life choices are so vastly different or maybe we've just both changed too much. I felt my life had more in common with Kelly's at the moment and she's a single mom...pretty far removed from my everyday existence.
I'm really having a hard time dealing with this in my mind. I don't like feeling uncomfortable around someone who is supposed to be a close friend. Sigh
