Someone on AskReddit asked for people to share the "little kid" things that they refuse to stop doing, even though they're expected to act like an adult. The daily grind of trying to make it in this world is hard enough. Let the people have their fun with treasured pastimes like Legos, sliding across wooden floors in socks, or using the force to open automatic doors like a total badass.
