These angels don't cover their faces out of pity.
The Weeping Angels on Doctor Who look like ordinary statues as long as you keep your eye on them. The minute you blink...
Far from angelic.
The Weeping Angel mug features a peaceful orchard scene - a bone orchard, that is - that transforms as soon as you add hot liquid.
Look away and they get closer...closer...quick as death and silent as the grave, until you look back and it's too late.
Fiends also have wings.
Did you shudder just now? A steaming hot drink is just the thing to take the chill off.
Remember: 1. Pour a hot beverage. 2. DON'T BLINK.
