I'm not sure I miss my childhood all that much, although there are some parts of it I wouldn't mind experiencing again. In some ways, I think I'm reliving the best parts of my childhood and teenage years now, as now I can do all the things I wanted to do then without having to deal with the negative stuff. If I want to stay up all night playing Super Mario Bros. 3, I can, and no one can yell at me for it, not even my parents. I can go to all the concerts I always wanted to go to when I was a teen, I can buy and wear whatever clothes I want, I can eat whatever I want, etc. Ahhhh, freedom. :D
