I'd say my best day(s) ever was when I was in 3rd grade, living in texas. I had a lot of friends, it was always nice outside, great family life, and everything I needed as a kid. I was always out riding around, chilling with friends, messing with fireworks, catchin' animals and much more.
It was the most memorable and nice period of my life. I don't really have a particular day, but overall it was all great.
