It is decent to be humble amidst great prosperity; but we can scarce express too much satisfaction in all the little occurrences of common life, in the company with which we spent the evening last night, in the entertainment that was set before us, in what was said, and what was done, in all the little incidents of the present conversation, and in all those frivolous nothings which fill up the void of human life. Nothing is more graceful than habitual cheerfulness, which is always founded upon a peculiar relish for all the little pleasures which common occurrences afford.
