Who's having a heat wave?
I had to put the heat on Saturday night, cold wind!, and it was bloody freezing Sunday night, had to get another blanket to put on the bed. Yesterday morning the weather was horrific (drizzly ,grey and gross and brrr).
This morning I went, brrrrrrrrr when I stepped outside.
Not too bad now, but I would not say that 14ºC is exactly tropical.
