Worlds Colliding

Do you know what is the worst thing about having such similar interests as your ex-girlfriend?

The fact that you know you will eventually run into her and her friends again since you both like similar events and locations. We both hit the same coffee shops, restaurants, and clubs/bars. I have been very fortunate to not run into her too much. Of course, I ran into her at a coffee shop one time and it didn't go to well. Since then, I have really avoided all the usual places like the plague. But now I really am tired of trying to avoid some of my favorite spots. I have been going to my usual locations again and wouldn't you know it. I've seen some of her friends lately. I don't know if they realize that I'm there and are ignoring me or if they don't remember who I am. Anyway, the point is I wonder if they tell her that they saw me or if they don't bring it up. After all, they are trying to make sure she is moving on so why would they mention it to her. I guess the real point of all this babbling concerns the fact that this may be happening to me. I wonder if any of my friends have seen my ex around town and didn't mention it to me on purpose. I don't really want to know if this has happened in the past or not. I was just wondering...
