How did that happen?

It is empty! Must be the Central Heating, only opened it half and hour ago, and now it is empty! Very nice though!
 We have a Severe weather warning for tomorrow night, minus 8 to 11°C and a possible 15 cms snowfall. Who said we won't have a Winter?. Long Range forecast for next week is still below Zero nights and 3 of the days too. The car stays in the Garage!
