I don’t have the Keys to the City, but I enjoy gallivanting about it as much as possible. What keeps me passionate about life? I have no idea; maybe it’s because I’m not afraid of looking silly and/or doing whatever it is I find fun.
I’m a fan of the adage: You don’t stop having fun because you grow old; you grow old because you stop having fun! When I think about it, in some of the most ridiculously fun times of my life, I was doing something many would think I had no business doing.
So, if I want to go with 100+ other people and have a marshmallow war, or a light saber battle, or dress up as Santa and run around the City, whatever…I do it. As long as you’re not endangering yourself and/or others and it’s relatively legal (*big gleaming faux innocent grin*), some childish things shouldn’t be put away, if you still enjoy them, whatever your age. Besides, if we live long enough to get to that rocking chair stage and "remembering when" it helps to actually have something worthy to remember and talk about.
