My daughter seems to have picked up a fear of spiders from her teacher, which I'm annoyed about. OK, if you fear spiders that's your concern, but if you are teaching small children you should in your professionaly capacity try not to transfer this behaviour to them and not overreact when you see a piddly little arachnid (as they generally are in this country). Say to the teaching assistant, "Mrs Homewood, could you please remove that spider", instead of, "Aaaahgh, get rid of it Mrs Homewood, get rid of it!". Now my daughter overreacts when she sees small spiders where she didn't previously and we have to try and reverse this behaviour somehow.
