The weather controls my mood, almost 100%

It is so beautiful in Chicago today, I feel so happy! My mood is noticeably better today. Not that it's bad on a regular basis (only sometimes), but the fact that I actually thought to myself, "wow, I am happy!" that says something! I'm pretty sure if it was cold and snowing, or even just cold, I would not be in a great mood. Probably grumbly, cranky, inpatient (a lot of that due to the CTA in the winter), and over all probably not a peach. It definitely makes me consider where I should live, and as much as I love Chicago... Is it the place I'm going to stay forever?
