he's out of town.
which seems like a perfect ;opportunity for a second date. in theory.
didn't we have a good time? remember that? our first date? back in the 40's? he's so agreeably genuine, she wants to let him down easy:
ooo.o, shit, the "so busy" speech -- stop -- not worthy of you. or me. i'm patient, so.  call me. when you're not busy.
i would so wait a decade for you. call me his sophomore year, i'll prove it. and with a smile he heads off. she watches him go -- dammit! really liking him in this moment. she watches longer than she should.  then goes back to her work. he gets in the elevator and she's left in her solitude. and now we begin to see the first signs of it: loneliness.
