He was one of those fellows, you know, who seem to care absolutely nothing about what others think of them.

It's all one if fellows hate them or love them, and as for being influenced by any desire to cultivate the good graces of one's neighbours, you might as well expect a bear to cultivate the good graces of a porpoise.
I soon began to suspect that Jack was not altogether comfortable in his new quarters, although he never hinted to the contrary.
