Obeying the laws of Thermodynamics

For my first official bloglet I have only one thought in my head.

Why is it my grandmothers house always conspires to be colder inside than it is out?
I have heard people blame the thick concrete foundation (we dont build our houses out of wood like those sissy American houses). I personally put a little bit of blame on these "patio doors" as I can feel the cold bleeding the heat from the room there.

But still, outside there is frost on the ground and I get the feeling I'd be warmer out there. When I get my physics degree, I'm coming back to experiment on this house.

That and steal that beanbag I've had my eye on for almost two decades.
