How Old Were You When You Finally Grew Up? [PHOTOS]

As the saying goes, you're only as old as you feel. That being said, how old were you when you finally grew up?  21?  30?  Never?  Personally my answer would be not yet, with no plans to do it any time soon.

Case in point, last weekend we rented a bounce house for my son's fourth birthday party.  At one point, I actually kicked the kids out and called for an "Adult Swim!"  The grown ups had a few minutes of playtime before I let the kids back in to tackle the adults that were still inside.  Later, the bounce house deflated with about a dozen kids inside, and I tried to blow it back up.

Today, I looked through my Facebook photos, and couldn't help but notice that I have had a lot of fun since I became an adult.  I'd be willing to bet that I've had more fun in my 20s and 30s than I did as a kid!  Having three kids makes it easier to cling to your inner child, but I'm pretty sure that if I didn't have kids I would be just as child-like, if not worse.

Take a look through these photos and tell me if you can relate.  Are you a big kid, or did you grow up?  If so, how old were you?  Chime in with your thoughts in the comments section below!
