Strange weather yesterday, Tuesday. On the awakening, a beautiful blue sky immediately enchanted my start of the day. Then suddenly, this sky became completely grey. A little snow even fell. I had an intervention in a recreation center to launch scientific challenges to children. In the early afternoon, I passed my professional evaluation with my supervisor. It went very well. On the way home, I got a nice clear sky, then big clouds, and finally hail. I was happy to go home where there was a good fire waiting for me.
