Hey, man! 28 is not old!! You'll see when you hit about 22 how much closer 28 is...and then 30.
And us saying "you'll grow out of it" isn't meant as an insult. It's simply true. We all did, and when people told us "you'll grow out of it", we didn't believe them...but we did.
here's a picture of me at 33:
I still feel "young". I play paintball and climb on rocks and go fishing...I just have a daughter and responsibilities now. Being older isn't a bad thing. You have more money to do the things you want to do, and nobody tells you that you can't do something. :cheers:
