Serce ludzkie bywa czasem tak zgłodniałe, że rzuca się nawet na kamienie, nie czując ich martwoty i chłodu.

If you do not want to work in the heat, you will have to starve in the cold.

I could forgive you even your cruelty if it were not for your calm.

Some days are diamonds Some days are stones Sometimes the hard times won't leave me alone Sometimes the cold wind blows a chill in my soul Some days are diamonds, some days are stone

(...) “to have a hairy heart” has passed into everyday wizarding language to describe a cold or unfeeling witch or wizard.

I have patience, but I will only wait so long, till my heart grows cold.
