Select and discuss a key incident in which a main character finds himself/ herself in some type of conflict?

The Guernsey Literary and Potato Peel Pie
Society, by Mary Ann Shaffer and Annie Barrows, is a series of letters
between Juliet Ashton and the other people in her life. We only know of anything that
happened to any of the characters through their correspondence with her, and there are a
number of what might be considered main characters.

Juliet
Ashton is the character who connects all the others, and she finds herself in a rather
unusual conflict when Markham V. Reynolds asks her to marry him. He is a spectacular man
in every way: rich, beautiful, cultured, and a book publisher. They do fun and exciting
things together, and she enjoys her time with him very
much.

However, they have only known one another for two
months, and Ashton does not feel that is long enough for her to be certain Reynolds is
the man she should marry. There is shouting and crying, but in the end Ashton asks him
for more time to decide and he gives it to her. Earlier in her life, Ashton realized she
was making a mistake the day before she was to get married, so she does not want to make
the same mistake again. 

It is an excellent choice, for
Ashton marries someone else.
