Neither did I. Just made that statistic up, in fact, but c'mon, don't tell me you were surprised. Think about it.
Love is weird.
Love is idiosyncratic. It's different for everyone, and produces different kinds of stories. Enter Valentine's Day. This produces a cultural, monolithic set of images about love which kill the creativity, spontaneity and sense of self that love thrives on. Instead of expressing real feelings, we fill each others' mailboxes with syrupy Hallmark cards, as if the miracle of caring could possibly be expressed by the underpaid 50 year-old hacks Hallmark employs.
