“G. is squirting water!”  A disgruntled student told the teacher

The teacher looked up and said “I wouldn’t be impressed by someone squirting water.  Are you impressed? I actually might be kind of upset if someone squirted me with water.”

The student looked at the teacher for a moment and then, realizing there really wasn’t any more to be said,  walked away.

The student resumed her work.  The teacher resumed her observations.  Water was no longer being squirted.

BOOM! The Montessori way!
