I think I'm officially a Chicagoan...

You know you're used to winter when:

1. You witness a 40-degree temperature increase in 24 hours...and it's still only 20 degrees.
2. While walking outside in said 20-degree weather (with snow falling), you announce "it's really not all that bad out here!"

I know what you're thinking: that I've officially lost my mind.  Don't worry - I was just thinking the same thing! :)
