I remember it. I enjoyed it. I sometimes enjoy remembering it.
But there are things that I don't enjoy remembering about it, and so, I don't think about it often.
Besides, I am not even the same person that I was then, nor are any of the people I knew at that time the same as they were.
Sure, I think about my girlfriend in HS sometimes. I sometimes even wonder how she is today.
But what would be the point?
