People spend their whole lives trying to be mature. Then you become mature, and have your midlife crises, where you try desperately to recapture your lost youth.
I'm still in that phase where I'm trying to be a grown-up.
A little while ago, I bought a ham. It's in my freezer right this moment. Having a ham in your freezer is definitely very grown-up.
Of course, I also bought apples simply because they were shiny. That might not be.
Sometimes I tell friends that I’d like to be an adult. And then I jump up and down, or something, just to demonstrate how eager I am to reach this goal. Most of them seems to think that I’m not, though.
Dave Cockrum, the guy who created the X-Men, died recently at the age of 63. They found him with a Batman blanket, wearing his Superman pyjamas. That’s definitely not grown-up. I wonder if he had a girlfriend? He probably didn’t have a ham in his freezer, anyway.
