Driving to Town Late to Mail a Letter

The title reminds me of someone realizing that they have a over due bill and hurrying to get it dropped off. As I read it though it seems that they are mailing a letter to a secret love. There is a lot of lonliness and secrets. The persona welcomes an "abandonded" street. Why was the word abandoned chosen and not empty? Choosing to mail a letter late at night while it is freezing and snowing is a good time to not be asked any questions. The persona used the word love to describe a snowy night. I think the word choices are hints. I think that the mailer of the letter has been abandonded but refuses to give up hope on lost love. The late night is the ideal time to not be criticized or thought pitiful. The snowy weather could also be a sign for lonlieness. Hemingway used rain to show something bad was about to happen, maybe Bly was using a similar technique. Another hint to this theory is the last line " Driving around, I will waste more time" The letter being mailed is a waste of time and it is known.
