"How I Met My Husband" is a short story written by Alice Munro, first published in 1974 as a part of her collection Something I've Been Meaning to Tell You.
Edie falls in love with him, but soon learns that he is engaged to another woman, Alice Kelling.
One day while Alice, Mrs. Peebles and the children were away on a picnic, Edie goes to Chris's campsite to talk with him.
Eventually, Edie realizes Chris will never write and marries the mailman, who believes that she waited by the mailbox for him every day, although Edie never tells him that she had waited for Chris because she likes "for people to think what pleases them and makes them happy."
