What does David think about while sitting and eating the Oatbread?

David was thinking about his good fortune.... food, drink, and shelter. It doean't get better than that!

The good woman set oat-bread before me and a cold grouse, patting my shoulder and smiling to me all the time, for she had no English; and the old gentleman (not to be behind) brewed me a strong punch out of their country spirit. All the while I was eating, and after that when I was drinking the punch, I could scarce come to believe in my good fortune; and the house, though it was thick with the peat-smoke and as full of holes as a colander, seemed like a palace.

 And the second mention of oat-bread....

I sat down to eat some oat-bread of Mr. Henderland’s and think upon my situation. Here I was not only troubled by a cloud of stinging midges, but far more by the doubts of my mind. What I ought to do, why I was going to join myself with an outlaw and a would-be murderer like Alan, whether I should not be acting more like a man of sense to tramp back to the south country direct, by my own guidance and at my own charges, and what Mr. Campbell or even Mr. Henderland would think of me if they should ever learn my folly and presumption: these were the doubts that now began to come in on me stronger than ever.
