Friday night lights.

I have never really understood the game of football. I always enjoyed going to a friends house for appetizers and cocktails on game night and cheering when "our" team scored but I've never understood the dynamics of the game.
My son started playing 3 years ago so I'm (very) slowly catching on but I still find myself asking the parent beside me "what was that call for?"
I enjoy watching the game more and more and I hope to eventually figure it out.
