Great post! Growing up doesn't mean you have to get boring!
( Although I have some inlaws that think it's the only thing that makes you a "grown up". ppppfffttt.
I'm 37 and I know the release dates of every near-future PS3 games by heart. I love watching cartoons, watching skateboarding events on TV, and racing those little cars around the go-kart tracks - and I don't drink coffee! Blah!
"Orange drink - orange juice, what's the difference?" as the kid in that commercial used to say!
You can grow up, without growing up - and you can love every minute of it. You just have to not give a rip about what other people think of you and your love of video games, skateboards or Foster's Home.
