But remember that the pain of parting from friends will be felt by everybody at times, whatever be their education or state. Know your own happiness. You want nothing but patience; or give it a more fascinating name: call it hope.
If friends disappoint you over and over, that's in large part your own fault. Once someone has shown a tendency to be self-centered, you need to recognize that and take care of yourself; people aren't going to change simply because you want them to.
Many merry Christmases, many happy New Years. Unbroken friendships, great accumulations of cheerful recollections and affections on earth, and heaven for us all.
