Betty When You Call Me, You Can Call Me Sir

I am proud to say that I have completed my soccer referee training, and I am now a licensed referee-- today I had to drive to Newark and do the field training, and I learned plenty: 

1) there are a LOT of nuanced flag signals for Assistant Referees to master;

2) do NOT blow the whistle when a goal is scored-- because you don't want to draw attention to yourself at a time when the players should be in the spotlight . . . just point to the center of the field, indicating that's where the restart will occur;

3) hold your yellow card straight up in the air, as you are warning the entire field of play what will and will not be tolerated;

4) do not wear your whistle around your neck; keep it in your hand, so as (and I quote) NOT to look like a "seventy-year-old-lesbian-gym-teacher."
