Tom Lehrer's tribute to Alma Mahler-Gropius-Werfel is magical. Absolutely worth the 4 minutes to listen to a woman who seduced most of the most creative men in the German-speaking world. https://www.youtube.com/watch?v=

Education for kids with special needs is one place where the best schools can be 100x a median school - it’s worth contacting the Perkins School for the Blind in Massachusetts to understand what resources you should be using now. Speaking a
