Big Brother

I was home last night playing strip solitaire after work, the game was just getting interesting when I got a phone call from an unknown number. It was a 702 area code, Las Vegas. I didn't answer the phone in time so I missed the call. They didn't leave a voicemail. Spades and diamonds were already on my mind, I didn't know what to make of it. I don't know anyone in Vegas, but they must know me. Did they somehow see me cheat just then? Can't I play by my own rules in my own house? I really don't mind being watched, but I've always hated bullies.
