Remember when?

Being a little kid, I always knew that eventually I'd grow out of everything that amazed me and that new things would catch my eye. Now, being 16 i've realized that although the former is true, the things i had found amazing when i was 6 still capture my interest, the only problem being that there is a fine line between whether or not this is acceptable or whether giving in to the childsih urges one has come to acquire over years of being "caged" into a responsible mindset, is in fact not acceptable and should be repressed along with many other things deemed unnecessary once you hit "maturity". Lately this has confused me because although the things going on in my life are in fact interesting and do keep me happy and amused, there seems to be a background need for something a little more childish, most likely because the fun had as a child was completely careless, as to the fun one is able to have whilst growing up is more directly emotional, and also involves having money to go out.
