Quick on the whistle?

[Adam]

Freshman boys game last night. H-team is crying a lot during the game about calls against them. After one foul on H, we're lining up for some V freethrows. H-1, in the bottom slot, swears in my ear. Whack!
Coach indicated to me after the game that he thought I was quick on that and should have warned the kids. Of course, coach also accused me of changing the flow of the game with that call (lost by 30) and asked me if it was something personal. Never had him before.
Thoughts?
