And me! I grew up in Australia (£10 Pom family) and I've never been warm since we've come back, and that's 50 years!
Summer of 76? I pushed the sleeves up in my jumper occasionally!
I cannot go out without taking a jumper/ cardigan/ coat "just in case". Used to drive my girls mad when I'd insist they needed a jumper or something.
I work in a supermarket and the air con is bloody cold, and I'm amazed to see people coming in in the summer and leaning over the freezers to cool down. I can't go halfway up the veg aisle when I'm shopping without putting a cardigan or jumper on.
Saying that, I love hot weather, bring it on.
