Driving to Town Late to Mail a Letter

Cold and snowy night, and the street is deserted... at the beginning of the poem you almost see something bad happening. Cold and snowy suggest a gloominess, but the poem is a pleasant tone. "Alone at last" the speaker seems to sigh. You wonder what letter is so important that it must be mailed that snowy night, perhaps a letter to a relative or love interest. The poem does not assign a gender to the speaker, meaning it could be anyone. A person simply driving to the mail box, alone, and seems to enjoy and crave the alone time. You wonder why they are driving alone and why they enjoy it so much.... but you can also relate. At times many of us crave to just be left alone! There are limited places though, sometimes there is no where to just be alone. On cold and snowy nights people just want to get home a fast as possible and sit with there families, but for the speaker this is a time that he or she can finally be alone and at peace.
