I always have. Growing up seems like moving on from certain things and adding on a lot of responsibility. Honestly, part of me would be quite content as a perpetual seven year old. (That would be the part of me that doesn't drive, vote or enjoy an occasional glass of white zin.)
There is a poem I read in, like, 4th grade or something. It was about a girl who was turning 11, but she looked at as adding an 11-year-old in to the mix with a 10-year-old, a 9-year-old, an 8-year-old, etc. So yeah, I am a 24-year-old, but I'm also all the ages I have been.
I guess my inner child just surfaces more often than most. Or maybe my outer grown-up just goes away from time to time. Which isn't always helpful. I can't always put responsibility on the back burner so I can watch my Disney movies, but...y'know...every once in a while can't be bad.

Yeah--the 'editing' sucks. I don't have photoshop, just paint shop...but you have to see the full panorama of this mug to get the effect.
And I'm going to Disneyland next month...I'm already gearing up!!
