The early sunset in fall and winter. I like when it's dark outside and you can see light in people's homes, it feels so cozy to me. Also hot water bottles, I love going to bed with one.
I also just love the long quiet nights of winter, in fact i wish i were able to experience the far north like yukon or oslo or something like that, possibly even further and experience not having the sun rise above the horizon for a few days, i think the lighting would be absolutely gorgeous
