this is a very unethical question. the middle of my "dvd" (..) had a glitch and i think i missed about 5 or 6 minutes. it's around minute 43. Matthew says "there's no bed in here" (he's talking about Maria's room) Maria's starts a reply, but then the glitch starts and it zaps to Maria doing laundry and talking to two people (one is Peg, the other says "i like being pregnant") about the possible abortion.
I have the DVD so I will watch that part and let you know. It is quite possible that is the way the movie goes though. There are a few scenes in this movie (and other Hal Hartley and Adrienne Shelly movies) that jump quickly on purpose....
it's a very important scene, so that glitch came at a really bad time. from what i remember, this is how it goes; Maria says "i'll sleep on the floor", they start talking about something else, matthew asks her if she's near sighted, she says yes and that she think she looks like a dorky librarian with the glasses on, he say he likes librarians, she starts wearing glasses, seems like he likes it, tries to kiss her, but no kiss happens, she ask him for his handgrenade, takes it and goes to her room. her mother yells from downstairs, talks to matthew who's still standing there and tells him to "not get any ideas" and he goes to his room(i think). cuts to marias room where it shows her putting the grenade in her drawer, and that she starts writing in her diary about how shes ashamed about some things, like being young (and something more i think). then she goes to sleep on the floor, aaand i cant remember any more.
