We have begun to slam doors, and to throw things. I throw my purse, an ashtray, a package of chocolate chips, which breaks on impact. We are picking up chocolate chips for days. Jon throws a glass of milk, the milk, not the glass: he knows his own strength, as I do not. He throws a box of Cheerios, unopened.
The things I throw miss, although they are worse things. The things he throws hit, but are harmless.
I begin to see how the line is crossed, between histrionics and murder.
