Such people, while useful, even agreeable, to others, are, if truth be told, frequently unhappy–lonely in fact. Yes, they seek out others, and it may even seem to them that in a certain country or city they have managed to find true kinship and fellowship, having come to know and learn about a people; but they wake up one day and suddenly feel that nothing actually binds them to these people, that they can leave here at once. They realize that another country, some other people, have now beguiled them, and that yesterday’s most riveting event now pales and loses all meaning and significance. For all intents and purposes, they do not grow attached to anything, do not put down deep roots. Their empathy is sincere, but superficial. If asked which of the countries they have visited they like best, they are embarrassed–they do not know how to answer. Which one? In a certain sense–all of them. There is something compelling about each. To which country would they like to return once more? Again, embarrassment–they had never asked themselves such a question. The one certainty is that they would like to be back on the road, going somewhere. To be on their way again–that is the dream.
