Have you ever wished you could return to your childhood for just a day?

I remember when I used to go over my grandma Louise's house and my uncle would play PC games with me. We would play Total Annihilation (with The Core Contingency and Battle Tactics), Carnivores, Total Annihilation: Kingdoms, Planet Hot Wheels, Civilization II (with Conflicts in Civilization and Fantastic Worlds), Descent (with Levels of the World), Descent II (with Vertigo Series), Descent FreeSpace: The Great War, RuneScape (we only played this a few times), Star Wars: X-Wing versus TIE Fighter, and various other games. We would also watch movies in his basement, I remember when we used to watch the first Alien movie. I was like 8-12 when we used to do this stuff. I remember when we went to a baseball game that was sponsored by his work and there was like this festival thing before the baseball game that was for employees (and friends and family) of his work only, I had so much fun. We used to do all this awesome stuff together and I looked up to him as a role model, and I used to spend the night at grandma's house like every other weekend. He even got me into a community college at the age of 13, where I still attend schooling at (separate from the two high schools and one junior high school that I currently attend; what can I say, I guess I'm a prodigy). He also taught me how to SCUBA dive (he is a professor at the college and one of the classes he teaches is SCUBA). He also took me to World War II reenactments, where I got to dress up as a n American (or was I British, I forgot) soldier and got to use a real gun (blank adapted). He also taught me how to fire a real gun. But now my uncle and like never do anything. I'm 17 now and we haven't really hung out like we used to (which is explanatory since I'm a teenager and have been for several years so now I'm more interested in girls, hanging out with friends, the SS Free, Facebook, computers, and video games, than spending time with family members). But I kind of miss doing all that fun stuff with my uncle, now I have torn him away from me too, just like I have torn everyone else who cares about me away. I tore my parents away (we never talk unless we are arguing or yelling at each other), I don't want to do anything with them (obviously), I don't even want to be seen with them in public (what teenager does). The only people I had were my friends, but even then I partially blew that when I fell in love with my best friend and she didn't love me back, which I am still recovering from). Do you ever wish you could just go back to the simple times of your childhood, just for like a day?Have you ever wished you could return to your childhood for just a day?
Although it's not gonna happen, I've wished.
