I haven't seen FUN HOME, but I just read the graphic memoir (graphic in both senses of the word). I, too, have my doubts that Bruce killed himself. The branches he was carrying could easily have prevented him from seeing the truck. Also, killing oneself by walking into traffic is both iffy and selfish -- that truck driver probably never got over what happened.
Probably, one of the toughest things for Alison Bechdel was not knowing what happened. If Bruce had been my father, I think I'd have hated him, because he comes off as an abusive parent, at least in the book.

Audrey, the Phantom Phanatic, who nonetheless would rather be Jean Valjean, who knew how to make lemonade out of lemons.
