- Yeah, you're probably right. But you have to remember that until just recently, this world was mine exclusively... Plus I really like your voice and if you're quiet, asleep maybe, a pinch or a hard caressing of your belly or face will usually make you snap out of it and start screaming.
- You're definitely right about that.
