Thanks. I asked that specifically because I've begun volunteer reffing AYSO games and I've already had some moments where I almost immediately realized I made the wrong call (no cards given tho) and kind of panicked about whether to correct it. When I did, the coaches always seemed to smell blood in the water (weak ref!) and the rest of the game was more difficult for me. But when I didn't correct it, I felt like I had knowingly cheated one side.
Every soccer parent should take a ref class and try reffing some games. I have a whole new level of respect for the job.
