Leave a freaking message. I’m getting really aggravated because my cell phone has been ringing all the live-long day just when I do something reckless like go to the bathroom or run to the basement, and whoever it is keeps hanging up right before I get there. I called back, and, being a civilized person, have left my name and number but there’s only so many times I can tell “Dave” that “This is Carrie, returning your call…” before I want to just leap through the phone and throttle him.
He’s apparently in Oconomowoc, according to his area code, which makes me think I must have left something there, but what? The only things I’m aware that we left behind are a couple of stuffed animals, but I’ve already contacted hotel housekeeping about those, and they’ll UPS them to us. (Gabe’s beloved stuffed guinea pig and stuffed duckling; unfortunately, the rubber turtle we also left didn’t show up, so I’ll have to get another one of those so he can have his “Wonder Pets” reunited.) I have my wallet and credit cards; what on earth would have my cell phone number on it? Grrrrr! 
Did you try Googling the phone number (with and without dashes)? It might provide a clue.
I did, but apparently it’s a cell phone.
The people at the gaming conference want you to be a spokes model?
