All the romance had come down to that. Now, on the upper Oise, where nothing sailed as a general thing but fish, a pair of canoeists could not be thus vulgarly explained away; we were strange and picturesque intruders; and out of people’s wonder sprang a sort of light and passing intimacy all along our route. There is nothing but tit-for-tat in this world, though sometimes it be a little difficult to trace: for the scores are older than we ourselves, and there has never yet been a settling-day since things were. You get entertainment pretty much in proportion as you give. As long as we were a sort of odd wanderers, to be stared at and followed like a quack doctor or a caravan, we had no want of amusement in return; but as soon as we sank into commonplace ourselves, all whom we met were similarly disenchanted. And here is one reason of a dozen, why the world is dull to dull persons.
