Tell the SS that your Dad’s come to the school, and he’s going to answer questions for ten minutes. Get them to write down any questions they’d like too ask him about you. T checks question forms then tells the SS that he’s/she’s going outside to send Dad in. T then comes back in as his/her Dad (a disguise would help- old jacket, pipe, hat etc.). SS ask questions about T. (They’ll probably laugh at first, but it’s surprising how quickly they’ll imagine it’s your Dad they’re talking to.
