Help with Questions to The Last Leaf : In all this I bear Todd no grudge

In all this I bear Todd no grudge. I have simply added him to the list of men who owe me a dollar and who have forgotten it. There are quite a few of them now. I make no difference in my demeanour to them. But I only wish that I could forget.

a] Why does the author say that he did not bear any grudge towards Todd? Does he really mean it?

b]Are there some other people who owes to the author? Support your answer.

c] Why does the author wish to forget the people who owes him? Is he really able to forget them?

d] If you were in author’s shoes what would you do to get your money back?

e] How far the title `My Lost Dollar’ is suitable? Can you suggest any other suitable title? Which and why?
