Inksplotter, i don't think anyone has said it should be banned, just that it should have been thought through better. When you're playing a trick on 250 young children, did it not occur to a single teacher, that one or two might be a little disturbed by it? A letter to the parents would have put the responsibility back on them to prepare or withdraw their child. The school wouldn't have had any complaints. Either way, the school was shortsighted, which isn't reassuring at a primary school.
