“Books are the ultimate Dumpees: put them down and they’ll wait for you forever; pay attention to them and they always love you back.”

“You don't remember what happened. What you remember becomes what happened.”

“Here's to all the places we went. And all the places we'll go. And here's to me, whispering again and again and again and again: iloveyou”

“That's who you really like. The people you can think out loud in front of.”
