I think now it's officially Christmas time, since Thanksgiving is over. The air is cold and crisp and trees in every neighborhood are lit up. Improv shows are plentiful and most are crowded since people want to get out of their homes but it's too cold to be outside. And the people of Chicago aren't bitter and depressed from winter yet. Let's just enjoy this time, until February and March when everyone has Seasonal Affective Disorder.
