Barb-I taught Emotionally Disturbed Studens (not as hard and bad as it sounds, often had same kids for years (they don't do major changes well, could teach with my eyes closed (same stuff over and over), but got first day jitters every new year. I think all good teachers who take it seriously and don't "coast" do. I could not do it now. In a chair I could never catch and restrain kids (as was needed sometimes) or seem to have abnormally good hearing and eyes in the back of my head, But I did love it! My students were wonderful (to me they seemed it) and I miss it.
