How are you an "older guy"? Maybe it's a bit late for highschool parties, but you're not old yet. I guess it all depends what you compare yourself to. People your age are not in the "older" category.
I have my friends and my daughters. I always make time for people when they do the same for me. I don't think we're too old. I think I'm too smart to get hurt again so staying single is for me lol
