But is it such a bad thing to live like this for just a little while? Just for a few months of one’s life, is it so awful to travel through time with no greater ambition than to find the next lovely meal? Or to learn how to speak a language for no higher purpose than that it pleases your ear to hear it? Or to nap in a garden, in a patch of sunlight, in the middle of the day, right next to your favourite fountain? And then to do it again the next day?
