Conversation Disability

I wouldn't worry about. As long as people aren't completely nudging you out of their "circle" or "fave fives" then you shouldn't have anything to worry about. I'd just pick whomever one person/persons I get along with the most and chill with them on a majority.

Without making a conscious effort to spend enough time with friends, you lose that sense of "closeness." All of my closest friends back in college were people I hung with on a daily basis.
