school for the blind

next week, i make my first trip to the school for the blind which i am scheduled to teach at once a month. my supervisor just got a lil info and relayed it to me. i am going to sing an english song i know in a costume for elementary school kids. it took me a few times, but finally i politely asked why in the world i would need a costume for blind kids. he laughed much, but still had no idea. this will be interesting...
