Stop being so weird!
I'm kidding. You're just maturing.
Work has been taking up a LOT of my time lately for a while now, I have barely been on BHW even, haven't been going out as much, yet when I do it's just how I remember it. Fun, refreshing, energizing, a good time, but nothing to get addicted over. I should make time for more leisure...
What I did notice is I am much more comfortable around people, much more "lively" and likely to talk to random people. Before it was me alone vs me in a crowd and though I've always liked being around people now both behaviors are much more similar. I like people and realized there is nothing wrong with that. Be a good member of your community, and this doesn't mean something like volunteering all the time(though volunteering is amazing fun), it just means to be kind and productive and at peace with yourself and surroundings and others. Go to a grocery store and just walk as if you were in your living room, at ease, but with pants on, and you'll notice how many people seem to be way too nervous and in their heads. You'll get stares and smiles. Life's about living, living is about being and sharing with one another. Sorrow comes from alone-ness(different from loneliness), but you will learn from it.
It isn't just you or people that have limited contact with others that are feeling out of place from the crowd, there is a general shift either towards a more "gossipy" life or a rejection of it and I would say the rejection is increasing regardless of what media or social media would have people believe. It's interesting.
