White Christmas? No thanks

Yesterday I left Switzerland with less than 5°C, and an all white landscape. Nice, really Christmaish, but cold, "effing" cold.

Today I woke up in Las Palmas de Gran Canaria, with 25°C, and an all blue wonderful sky. Nice, not Christmaish at all, but cool, "effing" cool.

:)

P.S: Around mid-day the thermomiter raised to 30°C

Time goes by (once more)
