I find it easiest to live with people that are different enough that you end up needing to use kindness to relate to each other.
After having felt isolated in my previous living situations, I'm now in a complex where we all hang out in the parking lot most afternoons. I'm a software engineer, my neighbors include bus drivers, clerks, landscapers, those who have no visible means of support, etc. It's a nice relaxed environment, which I don't experience when people who are too similar are around.
I have read that the secret of gallantry is to accept the pleasures of life leisurely, and its inconveniences with a shrug; as well as that, among other requisites, the gallant person will always consider the world with a smile of toleration, and his own doings with a smile of honest amusement, and Heaven with a smile which is not distrustful — being thoroughly persuaded that God is kindlier than the genteel would regard as rational.
To be hopeful in bad times is not just foolishly romantic. It is based on the fact that human history is a history not only of cruelty, but also of compassion, sacriﬁce, courage, kindness. What we choose to emphasize in this complex history will determine our lives. If we see only the worst, it destroys our capacity to do something. If we remember those times and places — and there are so many — where people have behaved magniﬁcently, this gives us the energy to act, and at least the possibility of sending this spinning top of a world in a different direction. And if we do act, in however small a way, we don’t have to wait for some grand utopian future. The future is an inﬁnite succession of presents, and to live now as we think human beings should live, in deﬁance of all that is bad around us, is itself a marvelous victory.
