time-to-spleen:

Headcanon that Tony Stark sometimes supply teaches tech/shop classes at local high schools for free when budget is tight, or to just give the teachers a break. He shows up and the kids lose it for a little bit, but then they settle down and listen. It gives them hope, because everyone always trashes the trades and people who work them, but this genius, billionare, playboy, philanthropist took time to teach them this class. He knows trades, and he thinks they’re worth something. He thinks these kids are worth something.
