“But though Death searched for the third brother for many years, he was never able to find him.It was only when he had attained a great age that the youngest brother finally took off the Cloak of Invisibility and gave it to his son. And then he greeted Death as an old friend, and went with him gladly, and, as equals, they departed this life.”

It might be nothing, but I‘d like to point out that Harry is wearing the invisibility cloak as he walks through the forest and only takes it off moments before stepping out to die at Voldemort’s hands.
