whqt did Pip admire about the pale young gentleman

Pip admired the boy's persistence. No matter how many times he got knocked down, he just kept coming back for more.

"But, he was on his feet directly, and after sponging himself with a great show of dexterity began squaring again. The second greatest surprise I have ever had in my life was seeing him on his back again, looking up at me out of a black eye.

His spirit inspired me with great respect. He seemed to have no strength, and he never once hit me hard, and he was always knocked down; but, he would be up again in a moment, sponging himself or drinking out of the water-bottle, with the greatest satisfaction in seconding himself according to form, and then came at me with an air and a show that made me believe he really was going to do for me at last."
