The man became agitated and began using foul language which concerned the teacher because of the number of parents and young children in the classroom.
She offered to call the child's mother to have her come down and sign the permission slip, as there was still approximately twenty minutes until the bus left.
She apologized for any inconvenience and reiterated that the rules were established to ensure the safety of all children.
The man was inside the classroom when the confrontation took place.
The resource teacher explained that because the child did not have a signed permission slip he was not able to go on the trip. The teacher told him that because he was not listed on the emergency card he could not legally give permission.
