Neil,
We can laugh and gloat when those in the Southern Hemisphere complain that 15°C is cold.
I do that regularly when my brother says "It's cold here", and then explain that 15° is normal, 20° summer, 25° heat wave and 25°+ end of mankind as we know it.
I used to complain as well, but I'm now fully assimilated into the UK weather, and now ready to complain about the heat.
