summer rain is awesome! Though I think my absolute favorite would be basically this:
I'm back home in Stockholm, and it's the middle of the summer. Only a few hours of darkness each night. I've been out with my friends all night, drinking, having a great time, until the bars close. It's 4:30 am, and I'm walking home from the bus station, and I'm walking thru the park, and I'm walking past the fields. It's pleasantly warm, I'm wearing a hoodie, birds are chirping and there's a thick fog. I've sobered up, but I'm not hungover yet. The sun has been up for just an hour or so. As I approach our house I'm met with one of our cats on top of the car. She's just as surprised to see me at this hour as I am to see her.
I can describe this so vividly because it's happened to me once already, and I think back on it once in a while. It's the most peaceful I've ever felt.
