The obvious reason is because Bing Crosby and company so romanticized the song that we all want one. Christmas cards and other winter scenes picture the pristine condition of the snow in a time when sleighs and carriages were popular -- not the muddy, driven-through mess that many of us have to deal with when the white stuff actually arrives in this day and age. As a Southerner though, I think there's another reason. We see so little snow that we actually want to see some. What better time than when family and friends are gathered and can stay inside and enjoy each other's company a bit more?
The weatherman has said that it will be too warm for a White Christmas this year. Instead, we're likely to have a rainy one. Am I being too bad when I hope that it's colder than the weatherman expects so that we can have that Christmas of which I dream and have only seen about three times in my entire life? If not, I may just have to mix three songs together so that I come up with "I'll have a White Christmas if only in my dreams."
