Maybe put socks and a jumper on before turning the heating up to 11?

Everyone’s boiling except one person who is wearing a t shirt and no socks.

11?

Spinal tap reference

Right?

If they pay the bills, they can do what they like with the heating thermostat.

Even so, It's not unreasonable to want some consideration of others comfort in the home.

That’s undeniably true.

can’t wait to get home!

Do what I do when DH does this - sneak upstairs and open some windows.

Although DH does have heart probs, so he's cold even in a heatwave...and I'm of a certain age where I can go from normal to strip all my clothes off in the freezer aisle of Tesco in 10 seconds.🥵
