“But there was a price. No-one asked you to pay it, but the very absence of demand was a moral obligation. You tended not to swat. You dug lightly. You fed the dog. You paid. You cared; not because it was kind or good, but because it was right. You left nothing but memories, you took nothing but experience.”
― Terry Pratchett, Lords and Ladies
