Grant request for Time Out?

[chels]

I had a highschool game last year and during the game I thought the coach was yelling for a timeout. I turned and
granted him one. He said he was yelling,"side out, a play".
I apologized, and resumed play. Unless I see the T sign
along with the verbal request from the coach I am not as
quick to stop play. Usually the players will look right at
you or try to hold the ball and signal at the same time so
that usually isn't a problem understanding them.
