In my case, I was born to parents who were very young, and I don't think they were entirely ready to have a child. My dad was going to college and working two or three jobs at the same time, and my mum was working and going to school.
I like today and perhaps a little future still, but the past is really something I'm not interested in. So, as far as I'm concerned, I like only the past of things and people I don't know. When I know, I don't care because I knew how it was.
