"Hi there," she says, her voice bright and enthusiastic. "This is Amy. Are you busy?"
I hear this voice once or twice a week, typically at 10 a.m. or thereabouts. The caller ID tells me the number comes from Texas. I imagine a stack of servers in a dark closet in a building on the outskirts of Dallas. I decide to have some fun.
"Amy, are you a robot?"
There's a pause, and for an instant I doubt my instincts.
Amy laughs. "No, I'm not a robot," she says, her voice bright and enthusiastic.
Shaken, I hang up.
