I was born in 84, and I rememebr a few years back, when a buddy of mine told me, "Do you realize that there are high school students...who don't really remember the 90's?" Blew my mind. Also, there was that XKCD where a kid tells someone presumablky around my age, "I am too young to properly remember 9/11, but I am still old enough to have a serious conversation with you about it". Also terrifying.
Also, I scared myself realizing that there would soon be a, "I Love the '00s" on VH1. It scared me even more to realize that I had similar feelings about a, "I Love the 90's" special back in 2001.
