For the most part, I was pretty completely bored by Other People's Love Letters: 150 Letters You Were Never Meant to See, edited by Bill Shapiro. It's not that I think gathering together other people's love letters, emails, and cards is a bad idea, it's just hard to really enjoy them out of context. (I have this problem often with the PostSecret books, where people share their secret thoughts, hopes, confessions, etc.; I much prefer the Found books, which are also random, but I prefer the "found" nature of the contributions rather than the "shared" type.)
(Below the greeting card picture of a cartoon man and woman in a tub with the sentiment "Happy Mother's Day, Honey.") "To my incredibly sexy wife,
You don't actually have to share the bath, as the picture shows, but since I know you're in desperate need of some relaxation (and getting into the bath isn't your idea of the most hygienic way to do it), this card comes complete with a promise from me to clean both our bathrooms thoroughly--including scrubbing the tubs. Love, Charles."
Boys, take note. THAT is how you write a love letter.*
*I also enjoyed this succinct but heartfelt email: "I don't know what got me higher last night all the herb we smoked or our kiss. We're gonna have to try both again so I can be sure. ;)"
