There's always a little truth behind every "just kidding", a little knowledge behind every "I don't know", a little emotion behind every "I don't care", and a little pain behind every "It's okay"!
I love the phrase "we're expecting" when talking about pregnancy, because it makes it sound like there's more than one outcome - "Yeah, we're expecting a baby.......... but it could very well be a Tyrannosaurus Rex"
