OK, so I don't have a hyperactive social life anymore. My twenties are long gone and most of my Saturday nights are relegated to home life. While many folks my age (I'm only 42) might still enjoy heading out to the bars and making casual acquaintances, their partners may not really appreciate that.
I realized today how much I like being a geek at home on Saturday night. It's relaxing and never really boring. Life is a hundred times too short to ever be bored.
