Officiating

I have to referee a high school swim meet tomorrow. It's my first refereeing assignment this year, and I thought I took notes after last year's Google incident, but if I did, I can't find them. I've been through a lot of notebooks since last year. Anyway, this time, I'm supposed to help train a freshman parent, and I think I'll omit to mention that I once had to Google instructions on when to blow the whistle. I want him to feel that he's in competent hands. Ignorance is bliss. Do as I say, not as I do.
