Most of our adventures probably seem that way to others. Our companions never seem to mind though.
Oh, yes. Weeping Angels. Quantum locked killers. See, when you look at a weeping angel it looks like it's just an ordinary statue - stone. It can't help it, that's just how it is. Eyes on it and it's stone. Nothing so scary about stone - a statue can't hurt you, can't even move. But, then you look away - then you blink - and they aren't statues anymore. Then they're the quickest, kindest killers in the universe. A touch from one sends you back in time, and then it feeds off of the potential energy from the life you could have lived.
They just send you back and let you live to death.
