I have a couple parents that are dropping their children off at preschool really early. Preschool starts at 8:00am while I don't have to be at school until 7:30am. Students are not to be here until 7:45am at the earliest. 7:30-7:45am I use for planning and prepping for class. I usually do most of my copying during this time because it's the only time the copier does not have a line. The other teachers are usually at the church getting ready for mass. I had a student show up at 7:33am this morning. I am in a separate building from the elementary by myself. The copier is located in the elementary. I am not allowed to leave the students unattended in my building or take students over with me while I make copies. So this morning I was unable to make my copies. The parents of this child have no other children in school and do not work until early afternoon. They have absolutely no reason to drop the child off so early. How do I explain to them nicely not to drop their child off so early?
