It looks to be a beautiful weekend to play soccer. Lets keep it simple and go back to basics. 

1) Stay close to the ball and position yourself to see fouls.

2) Don’t be a center ref. Run with the play. 

3) Introduce yourself to both coaches

4) Call a handful more fouls in the game vs a handful less. I never get complaints about a ref calling too many fouls. 

5) Be Professional, wear the full referee Kit. 

Above all, have some fun!
