“The years had not changed him much. Petyr had been a small boy, and he had grown into a small man, an inch or two shorter than Catelyn, slender and quick, with the sharp features she remembered and the same laughing grey-green eyes. He had a little pointed chin beard now, and threads of silver in his dark hair, though he was still shy of thirty. They went well with the silver mockingbird that fastened his cloak. Even as a child, he had always loved his silver.”

A Game Of Thrones, George R.R. Martin
