Polysemy justifys Matt's teaching lesson and in fact, there are stories in our canon that do what Matt is teaching...James's "The Turn of the Screw" but ugh, I don't read James well despite the fact that Leon Edel is such a great critic and would instead suggest looking closely at Poe's "Telltale Heart." With Matt's lesson about ambiguity and our valuing polysemy, the story can "work" with a number of possible meanings and so that there are several owners of a heart that tells tales, including readers' hearts! will ps no, polysemy is not a weird sexual act but it is my favorite word simply meaning many meanings...
