Why do so many people hate the cold, but love the snow?

Every year about mid-summer, people start wishing that it would snow because they are sick and tired of the heat. Well, a few months down the road it starts snowing and they are happy that there is finally snow, but they are ready for warm weather. How is that even possible, they complain that they don't have it then they get it and complain. In Psychology we learned that when there's not very much sunlight people tend to get depressed more easily than normal; and during the winter there isn't a whole lot of sun. I can't complain, I'm like most people, after a certain amount of time I'm ready for the cold to be gone and welcome warmth. However, if people can just be more accepting of what they have and not complain than life would just be a whole lot easier.
