Mommy 613- sorry to disapoint you, but don’t think for a minute that your kids are never involved in pranks.
School pranks don’t mean chutzpah. Sometimes they can be cute and done to the right teacher that enjoys them.
Sometimes they are performed purim time when teachers specifically give permission.
Whatever the case is, students definitely need to be careful with chutzpah but sometimes pranks are cute and really not minded by the teachers.
