Yeah, I remember when I turned 21 too. I think the only thing you can't do yet is drive a rental car, which you have to wait until 23. Then again, I am 23 myself! Of course, this was a great cartoon. I feel it's one of your submissions where we really get in your head and understand what's going on in your life. You are one of the most prolific creators on this website of course.
I am sure you will find love someday. Hey, maybe your female friend, eh, I'm just kidding. I like how you (as a cartoon character) looked so stern all the time while maintaing a silly overtone. Here's to more years of making great cartoons! With your other birthdays being celebrated, it doesn't look like you'll be retiring anytime soon.
