When out of the corner of my eye I spot something that shouldn't be going on, I can send a sign language "no" that direction without even missing a beat or saying a word.
If I'm reading with some readers during a book club and someone walks up, let's me know with sign language that they need to use the restroom, I send a sign language "yes" their direction, and my group wasn't the least bit interrupted.
While sitting in an assembly and a bottom forgets to sit on its pockets, without being disruptive I can send a "sit" in sign language even though I'm ten feet away.

I might suggest trying these out if you don't already. They're great, simple, and effective tools to add to that managerial toolbox. It can never get too full!
