I could give you a score of proofs.

Let us take his treatment of Aaron Latta.
One day about this time Tommy found himself alone in the house with Aaron, and had he been the old Tommy he would have waited but a moment to let Aaron decide which of them should go elsewhere.

It was thus that these two, ever so uncomfortable in each other's presence, contrived to keep the peace.

Now note the change.
"Aaron," said Tommy, in the hush that had fallen on that house since quiet Elspeth left it, "I have never thanked you in words for all that you have done for me and Elspeth." "Dinna do it now, then," replied the warper, fidgeting.
"I must," Tommy said cheerily, "I must"; and he did, while Aaron scowled.
"It was never done for you," Aaron informed him, "nor for the father you are the marrows o'." "It was done for my mother," said Tommy, reverently.
"I'm none so sure o't," Aaron rapped out.

"I think I brocht you twa here as bairns, that the reminder of my shame should ever stand before me." But Tommy shook his head, and sat down sympathetically beside the warper.
