<human>: This happened in fall of 2012. I live in chicago and it was one of those windy, freezing days. Anyway...

Im getting ready for my 8:30 class and its about 7:20 something. I'm putting on my jacket and figured, "I'm only walking the dog a short distance today, i don't need my coat" -.-' I finish walking the dog and I get back to the front door of my house. I open the screen door and get ready to open the big door, there are no keys in my pocket. I panic and search every pocket I had until I realized, they are in the house. So I ended up having to walk about 7 blocks on the south side of Chicago to my brothers high school with my shitzhu in tow at about 8am in a little ass jacketon a cold Chicago day. Got back home, got my keys, had to go back to give my brother his keys and was done by 9 and. Missed a test that day. Froze my nuts off. :C

Can you condense the text into a few key points?
<bot>: Left keys in coat. Had to trek to get brothers keys. Bring them back to him. Miss class and test. While freezing balls.
