feeling cold in a hot weather?!

My desk is by the window. You’ll see the tress and even the cars passing by. I felt cold around noon today for whatever reason… I really don’t know. So to help ease that feeling, I turned on the wall heater I have near me. Yes in the middle of summer! Haha! I was planning on turning it off after a few minutes but I completely forgot. Then, 2 of my co-workers walked towards the window and one noticed it and asked... "Is that heat coming out?". I felt so embarrassed but didn’t really take it seriously. I thought that’s funny! :)
