Wen I was in Kindergarten, my teacher called in my parents to tell them that I had learning difficulties. My mother asked why the teacher felt that way, her answer: 'He won't sit on the mat with the other children for story time'.
My mother asked the teacher, 'Have you asked him why he won't sit on the mat? he usually loves stories at home.' She called me over in front of my teacher. 'Why won't you sit on the mat with the other children for story time?'
'I don't know how to cross my legs' I replied.
Children are people too, sometimes it's okay to talk to them.
