I haven't done my 15x2 yet but have had lots of exercise at school even though it's been TOOOOOOOOO hot to move. No air conditioning there!!

I taught at home too for 3 hours and very annoyingly the air con has been out of action for 2 weeks now, so have had to resort to the electric fan, not the same.

We installed the AC 3 years ago when the neighbours complained about the music one hot day in June,

so with double glazing and aircon we can usually work without worry that we're a nuisance!!
