I've come to the conclusion, I like all seasons, but by the time the next one rolls round, I've got bored of the last one! So now, I love Autumn, I love browns and reds on the trees and mirroring those muted colours in my clothing (I really suit Autumnal colours!). I love being back in boots - I cleaned off my chipped toenail varnish over the weekend, didn't get round to repainting and realised I probably won't need to bother for months!
I like the temperature change, last week when it was hitting 31 degrees round here it was too hot and I realised I'm done with that sweaty feeling, I want layers and being able to control my temp by taking a jumper off rather than having to go have yet another shower.
My hair is like straw after a summer of washing it at least once a day and being in the pool so much, I want to get back to having sleek hair, to putting my foundation on (rather than tinted suncream) and it staying put all day.
Obviously, once the novelty has worn off, I'll have had enough of autumn, but then I'll have Christmas to look forward to. Hopefully we'll get some snow in January, by February I'll have had enough of winter and will be whinging, and then lo, Spring will be round the corner and I can start thinking about pastels and sunny days that aren't too hot and getting stuck in the garden, then by the time I've had enough of that, it'll be buying new summer sandals and maxi dresses and thinking about holiday packing... 
Basically, I'm like a small child who needs constant novelty to stop me getting bored, and this country's climate gives me that. I like the way Britain changes properly between the seasons, we live in such a beautiful country, and there's different types of beauty in each season. Even rain can be beautiful and dramatic. (And this is my first Autumn for fucking years without a buggy to push so I can carry an umbrella easily!)
