The Memory of Now

What do you think of you, now? What did you think of you back when you were a teenager? When you look back from now, what do you think of you when you were a teenager?

I have a serious lack of connection to my past.

That is to say, I have vivid memories of being me in, say, 1985, but not of what was happening around me so much on a day-to-day basis. I couldn't, for instance, tell you what classes I had in my junior year and who my science teacher was. I can, however, remember various teachers well and I can probably still do a pretty good impersonation of them.
