Social Retard or The Lone Ranger?

I've started noticing changes in myself. Not weird "I've grown a third ass cheek" type of physical change but more like changes in how I view life in general. It seems folks, that I'm enjoying time spent with ME. Me has become one of my closest new friends. Me and I enjoy taking long drives together, watching TV together, even showering together. Me doesn't think my sense of humor is weird or geeky; in fact, Me actually finds me quite funny! Me lets things be. She doesn't pressure me or make me feel guilty for spending a chilled out evening at home. Me understands me.

Now, I'm not saying that I've turned into a homebody (not that there's anything wrong with that). It's more that I don't find the need in doing those things that are so common in twenty-something land. The "Woo hoo! Alright! Let's get PLASTERED this weekend!" mindset. The need to expand the social circle to 500 people as quickly as possible. The frivolous conversations with random people while one shoulder surfs in search of a more interesting, frivolous conversation to join.

Am I getting old or older?

As I near 30 it seems that I've kind of, unintentionally, reevaluated my life and altered it without any need to consult myself. And I'm totally fine with that. I still enjoy going out but rather it be with my fiance (when I get to see him) or with a few close friends. I'd rather have deep conversations about random things while grooving to sweet music than packed in some overcrowded, over-amplified bar, squeezed in next to a guy who's sweat keeps dripping down my arm. I enjoy spending time with my family and appreciate them more now than I ever did.

Is this a normal transformation or have I jumped the gun by about 10 years?

Enlighten me, thirty-somethings!
