I played at a walk-on day at Weekend Warriors, Reading, and everyone was friendly. There was an incident where someone wanted to 'go out to the car park' to settle an incident, but he soon left, and everyone was chatty and friendly again.
It's ironic that we dedicate our time to hitting one another with paint, lots of paint, and yet off the field we are all pals. It says a lot for the sportsmanship of most players.
