A Glowing Future (Keiko)

Well, I thought the accident like this story could be happened truly (except killing somebody). Betsy and Maurice (and Patricia) are ordinary. From the first, Maurice had been very rude to Betsy.How could he come back to Betsy's house? As he said (felt?), he shouldn't have come back if he doesn't want to argue and explain about Patricia, but he came back and slept with her.I still can't understand that. Maurice made Betsy upset on purpose a lot. He was rude to not Betsy but also Patricia very much, I think. Therefore I understand why Betsy attacked him. Of course she shouldn't have killed him and to send the dead body to Patricia is very horrible!!!
