On static electricity...in the triboelectric series, our hands rank top so whenever we touch something that conducts, electrons jump from us to the object and we feel the static shock. And we end up positively charged. I suppose I conserve electrons better than Jo, because she's twice as likely to feel the shock than me. Haha. So when 2 people feel the shock upon contact, 1 has given the other some electrons. Interesting to know. It's more obvious in winter because the air is very dry. In summer, the air is more humid and the water in the air helps electrons move off us quickly so we do not build up as big a static charge.
On snow...frozen rain = sleet while frozen water vapour = snow. Cold temperatures change water vapour in the atmosphere directly into the solid state of ice (bypassing the liquid stage), creating snow that falls out of the sky. If the transformation happens closer to the ground on a cold surface, frost is created.
Our central heating has screwed up again :( And my voice is not back yet :(
