Definitely fall into the old when young and young when older category. I was a latchkey kid so I had a lot of responsibilities growing up and was very independent. When I was in grad school tho, I hit this state of arrested development and started getting back into some childhood interests like comic books and toys. I think the stress of higher education caused me to escape into old comforts. Since I graduated several years ago, I’m finally sort of getting back to “adulting” again after several years of indulging in minimal responsibility bachelorhood.
