"Lending Out Books," by Hal Sirowitz, from My Therapist Said

Lending Out Books

You're always giving, my therapist said.
You have to learn how to take. Whenever
you meet a woman, the first thing you do
is lend her your books. You think she'll
have to see you again in order to return them.
But what happens is, she doesn't have the time
to read them, & she's afraid if she sees you again
you'll expect her to talk about them, & will
want to lend her even more. So she
cancels the date. You end up losing
a lot of books. You should borrow hers.
