Am I the only one who does not think Aziraphale was going to say "I love you" right before he says "I forgive you"?

Sir Handel is tired and decided to take a rest by the tree stump. He feels self-conscious about his steam-roller wheels. Look at how mad he is when he takes his shoes off.
(I think Sir Handel looks nice with his wheels, and shouldn't have anything to be mad about. But, he's just a little grumpy-old man)
