and I love this:

"You have to be like a panther. Kinda approach it straight but with quiet grace. They know you are coming, they see you, and yet its up to them to let you touch’em or not. Truly instinctive and totally based on trust. If a blue see’s no danger on your moves, they stay. Even if it means risking their lives, they do it just for the sake of beeing touched by a human."
