I don't speak to them, don't interact with them, and we don't even have friends or even friends of friends of friends in common.
Then again, I've been with my husband for 15 years now, so it makes sense.
I guess if I ran into any one of them, it would be neat to see where they are in life, and I would hope they are happy. So, I guess I don't hate them. (I never really thought about it, go figure!)
