Don't Make any Sudden Movements

I was subbing at an elementary school the other day when a second grader came up to my desk and asked me permission, in Hebrew, to "_________" (can't remember the word). I asked him to repeat it, and he did. Then I said, in Hebrew, "I'm sorry, I don't understand what you're asking."

"A-ni Ro-tzeh La-a-sot Ka-ki," he said ve-ry slow-ly for those in the cheap seats. Where I was sitting the whole day.
