Freezing and it's supposed to be 100 today

I made the mistake of wearing a short sleeve shirt today, since it's supposed to be 100. It's simply too cold for short sleeves in our office, and I'm cold. I could bring a jacket, but c'mon...

So what becomes of my many short sleeve shirts? Are they all relagated to weekend duty? If you can't wear them on 100 degree days when can you wear them?


I don't have the answer, but for now I'm gonna go walk in the warehouse for a few minutes to thaw.
