It's like a warm, dry grass smell.

Okay. I get you now. Summer smells because of the heat on the grass. Winter just smells in the air, which is why I think it's cooler smell-wise.

But mum doesn't like it, ever since I fell, erm, through the roof at our old house and split my head open.

Ooh! Cool! Ouch! Yay roofs. I never go up on ours, though, as it slants pretty ferociously (not so much that you couldn't balance, but if it's even the least bit slippery or there's a leaf on the roof and you step on it. . .).

I am putting off my English essay.

Yay putting off English essays. I'm always doing that.
