What a difference a day makes...

Came home rather out of shape yesterday. Did not get better during the night.
Is it coming flu, or a severe cold combined with being exhausted from 4 active days in London? The order I got from Mrs B was clear. Stay in bed and keep warm. My blip is what I see from my bed. From my window I see blue skye and white new snow. Minus 8 outside. Get sicker to look at it. No spinning tonight either.
