too gentlemanly in manners
...Thoreau's Journal: 03-Jun-1857
I have several friends and acquaintances who are very good companions in the house or for an afternoon walk, but whom I cannot make up my mind to make a longer excursion with; for I discover, all at once, that they are too gentlemanly in manners, dress, and all their habits. I see in my mind’s eye that they wear black coats, considerable starched linen, glossy hats and shoes, and it is out of the question. It is a great disadvantage for a traveler to be a gentleman of this kind; he is so ill-treated, only a prey to landlords. It would be too much of a circumstance to enter a strange town or house with such a companion. You could not travel incognito; you might get into the papers. You should travel as a common man. If such a one were to set out to make a walking-journey, he would betray himself at every step. Every would see that he was trying an experiment, as plainly as they see that a lame man is lame by his limping. The natives would bow to him, other gentleman would invite him in to ride, conductors would warn him that this was the second-class car, and many would take him for a clergyman; and so he would be continually pestered and balked and run upon. You would not see the natives at all. Instead of going in quietly at the back door and sitting by the kitchen fire, you would be shown into a cold parlor, there to confront a fireboard, and excite a commotion in a whole family. The women would scatter at your approach, and the husbands and sons would go right up to hunt up their black coats,—for they all have them; they are as cheap as dirt.
