In Frankenstein, how does Walton define a friend?

Question

It's in letter 2

Answer 1

Walton expressed his need for a good friend in one of his letters to his sister, “I have no friend, Margaret: when I am glowing with the enthusiasm of success, there will be no one to participate in my joy; if I am assailed by disappointment, no one will endeavour to sustain me in dejection.”
