You can if you like.

Yup, I wore a Christmas jumper to my new job today. My office is freezing and this was the warmest one I have! I forgot how itchy it could be though...work was better today, I really wasn't enjoying it at the start of the week. I pretty much know what I'm doing already though, which takes the fun out of it. I'm knackered. Valentine's day tomorrow, I really hope I get flowers...
