Twice (recently) I have had teachers, from classrooms next door/ across hall, come in the class that I am supplying teaching in, without saying a word to me. One proceeded to look for things in the cupboard while carrying on a conversation with some of the students. Another proceeded to ask the class where she might find a broom to clean-up her class. On another occasion, I supplied for the afternoon as the regular teacher had to go for a meeting. He was there when I arrived in his class. He proceeded to take attendance, introduce the movie to the class, started the movie and left. He did not bother to ask my name? introduce me to the class? That day, I really felt like a NOBODY?
