PS My senior moment yesterday while sitting in the Home Depot parking lot:
Me: Headed home, Honey.
Wife: Did you find what you were looking for?
Me: Yep. And it was even cheaper . . . Dadgumit!
Wife: What's wrong?
Me: (Flustered) Hang on!
Wife: What's going on?
Me: Dang it! I can't find my phone!
Wife: What?
Me: My cell phone's missing! I must've left it in the store!
Wife: You serious?
Me: Yes! It's gone!
Wife: (Pause) Uh, you do know you're talking on it, right?
Me:
Headed home, Honey.
