So the cosy steaming mug brigade can shove their pumpkins up their arse!!!
It's not so much that people cant enjoy it but the constant wishing life away is quite depressing.
Er... you do realise that just because some people prefer autumn to summer, that doesn't actually make autumn happen more quickly? The Earth doesn't orbit the sun more quickly because someone says the word 'cosy' or expresses a love of hot drinks.
People 'wishing life away' doesn't actually make anyone's life pass any more quickly, and I don't really see why looking forward to something is any more depressing than clinging on to something that's slipping away. Absolutely fine if you hate autumn, but the fact that someone else might enjoy it has zero impact on you, so it's really fucking weird to get so cross about someone liking hot chocolate and cardigans. I don't like summer very much, but I'm perfectly happy for other people to wax lyrical about it.
Anyway, to answer the OP's perfectly normal, pleasant question - my favourite thing about autumn is when you go out in the morning and there's a bit of a chill in the air and it's sunny, but there's also some mist about. I enjoy going for a run in autumn and winter much more than I do in summer - an evening run when it's dark and cold is one of my favourite things, I find it much more satisfying and invigorating than running when it's warm. I also like it when it gets dark earlier, as I'm not a big fan of light evenings. Light evenings just feel a bit unsettling and harsh to me, I don't know why. Dark evenings seem much more atmospheric and interesting and I like the general eeriness - I'm a big fan of reading ghost stories and gothic fiction and that tends to lend itself well to autumn and winter.
