When you consistently find yourself starting a sentence only to forget halfway through what you were going to say.
Or when you know that there was something important that you needed to tell your babysitter but you can't remember what it was (hopefully it wasn't that important).
Or when you're choosing not to participate in KCW (and actually didn't even know it was coming up. See? I've obviously lost my mind!)
But still, life is good. Summer is good. All is good.
I hope it is with you as well.
