Because I am refusing to close my windows at night I was woken up by the cold around 6AM this morning. I covered myself with a couple of blankets and turned off the fan in the window and went back to sleep until the alarm went off.
I got my first Pfizer vaccine yesterday. My arm was a little sore towards the end of the day but that was the extent of any side effects.
Today is a nice day. The temperature says it's 50°, but it feels warmer. I think I'll open up the window. Good idea.
