I watched a trio of middle school age kids - a boy and two girls - for a while as they postured and did the stuff kids that age do when they're becoming self conscious about hanging out boys and girls together.
The boy and one of the girls took off up a side street while this girl lingered behind - to spy. Behind the blinds at work, unnoticed as adults often are by kids, I spied on her and took a voyeur shot. I spy on you spying.
