XXXIII.
Do not consider it to be at all times your bounden duty to correct every mistake which may be made in your presence as to a name or an unimportant date. Some persons are so extremely sensitive on these points that they never allow the offender to escape a summary conviction. However interesting the conversation may be, they always feel justified in interrupting it if they can show that the anecdote which they have cut short related to the late General A., and not to his brother the admiral.
XXXIV.
If one of your party should be prevailed upon to sing a comic song for the amusement of the company, he will of course do it as well as he can, and it would not be flattering to him that you should immediately afterwards talk about the great pleasure which you formerly derived from hearing the same song sung by Mathews, or Bannister.
XXXV.
Beware of the amiable weakness of repeatedly telling long stories about your late father or uncle. They may have been excellent persons, and their memory may be deservedly respected by you; but it does not therefore necessarily follow that a full account of everything which was said or done by either of these worthy men on some trivial occasion should be very interesting to other people, not even to such of your friends as may be lucky enough not to have heard it before.
XXXVI.
If you should have lately suffered any great reduction of income from causes over which you had no control, it is better that you should bear your misfortunes quietly than that you should be very extensively communicative to your acquaintance on the subject of your grievances. If, for instance, you tell them in confidence that you now have only 600l. a-year to live upon, such of them as have but 500l. will perhaps think that you still have at least 100l. more than you ought to have.
XXXVII.
Do not think yourself an accomplished traveller merely because you have visited places where you might have acquired much information. Many a man has passed some time in a foreign town without learning more about the beauties of its cathedral or the manners and customs of its inhabitants than was previously known to others through the instructive medium of a book and pair of spectacles at home; and therefore although you may have really been at Rome, and may have actually seen with your own eyes both the Apollo Belvidere and Raphael's Transfiguration, you must not, on that account only, consider yourself qualified to take a leading part in every conversation on subjects connected with the fine arts.
