If you have to stop play because of an outside force while one team has clear possession of the ball a good fair referee will drop the ball at such an angle so that that same team gets the ball back or even do a one player drop ball. The referee is part of the field. A ball that hits the ref plays on as if nothing happened. If it hits the ref and then bounces into the goal it counts as a goal. Move around the perimeter of the play.
Nothing looks as bad as a referee who tries to call the whole game from the center circle.
The league is paying you to be in the correct position to make the call and that position should be no more than ten feet from where the ball is in U6 or U8 and no more than 20 feet in U10. Smile and be helpful. Do not intimidate the players. Be helpful to the coaches, too. Most are new to the rules of soccer.
