Browsing around old posts on some sites turns up some gems. What a fun analogy!

“Think about it – there are a lot of similarities between picking a mate and picking a book. Your eye may land on a handsome volume at random, or you may hear about a promising one through a friend whose taste you respect. You pick it up and take it home with you to evaluate further. The relationship might be fast and furious, or it may end up being something you savor, or – even better – a love that you return to again and again over the years. Or it may end up being a complete waste of time. You just never know until you investigate what’s between the covers.
“Relationships with books actually have some pretty compelling advantages over relationships with men. With books, it’s always your choice if the liaison ends prematurely. You don’t have to worry about the awkwardness of trying to avoid your discarded book should you bump into it in the grocery store. You can tell it, “It’s not you, it’s me” or even “You know, it actually IS you” without hurting its feelings. It will also never insist on an exclusive relationship, and no one will think ill of you if you love more than one. You can take one to bed with you the very first night you bring it home without your mother blinking an eye.”
