My childhood

I haven't got many memories about my childhood. I only know, I was a good boy, and I was very different than now.  I liked to play football, and I was drawing all the day.
I was a good person, I always helped everybody. I remember, I was happier than now, because I didn't have problems, all things were better. I remember than I was always playing football in the street, and I never played Tv or the computer, now the things are very different. I remember that when I was 10 years old, I was some excited to do the communion, but now, if I was in the past, I will not do it because now I don't believe in God.
I want to go to the past to can change something, but I know it's impossible.
