" Then she wound up the clock. Witches didn’t have much use for clocks, but she kept it for the tick…well, mainly for the tick. It made a place seem lived in. It had belonged to her mother, who’d wound it up every day. It hadn’t come as a surprise to her when her mother died, firstly because Esme Weatherwax was a witch and witches have an insight into the future and secondly because she was already pretty experienced in medicine and knew the signs. So she’d had a chance to prepare herself, and hadn’t cried at all until the day afterward, when the clock stopped right in the middle of the funeral lunch. She’d dropped a tray of ham rolls and then had to go and sit by herself in the privy for a while, so that no one would see. "
