I don't want to grow up!!

So, I have been thinking a lot lately at were I am in life, and where I was before I met my lovely wife. Before I met her I was a college dropout working at a golf course for minimum wage. I was living in a apartment with a friend, who was a waiter, and drinking quite often. Not much motivation or direction in life when I look back. I met my wife and needless to say I got my ass in gear. I am a college graduate and currently have passed 3/4 of the cpa exam. I have a great paying job and a nice home. I would have never foreseen back in the dark ages (what I call the before I met my wife days)that I would reach the enlightenment (after wife era).

Since I have reached this enlightenment era there are a lot of people who have told me they are proud of me. Many have said "you've grown up so much." This brings me to my point. What does being grown up mean? I must say I am a little lamer than in the dark ages, but I don't care I like being with my wife. Does being grown up mean lame? If this is so I never want to grow up. Does being married and having a decent job mean I am grown up? I don't think it does. I still laugh at fart jokes and Family Guy. I like being irresponsible for my actions because I was drinking. I still look to make people laugh as much as possible. I swear too much. Some days I want to drink at noon (I don't anymore because I fall asleep at 6, might be part of growing up). So after all this, am I a grown up? In my opinion, no. I don't think I will ever fully grow up. It just isn't in my nature. My dad never did. My mom can still relate to her hippy days. So I may never fully grow up. The question is, what is the definition of grown up?
