In winter seeing the full structure of trees can be a really good sight, especially after snow when every branch is accented in white, but not as good as the sound and sight of a big tree in full leaf, in the wind. Sounds like the sea and I miss it once the leaves are gone.
I've said it before but I'll say it again, candles suit the autumn/winter mood for me.
Had a debate with my daughter about whether you get pink leaves in autumn, I was sure not, but we were in the park and sure enough some of them I couldn't deny were partly pink. New idea for me (brown, red, orange, yellow in autumn- it turns out is a myth)
