Sounds are interesting. They're all around me all of the time (almost), but I don't really think about them (unless everything suddenly gets very quiet). The only real silence I know is when you go to a concert (classical, with a big symphony orchestra). Then, right after they've finished a piece, there's real silence for some seconds, before the applause. Sometimes, I love that silence even more than the music.
In my room (or studio I guess... I live and create stuff in the same room) I can always hear sounds, though I generally don't listen to them. If I want to listen, I put on a CD book (right now I'm listening to Juloratoriet, by Göran Tunström), or some music.

Otherwise, there's sounds coming in through my window (I always keep it open). We live next to Årstabron (Bridge of Årsta - actually there's now two of them, though you can't see the new one from this side, which is good cause I prefer the old one), and there's trains passing at least every 15 minutes, even at night. As I've lived here all of my life I'm used to it and don't really hear them. But I like them, hearing them means that I'm home.

Now in spring, there's also the birds singing, which is lovely, unless it's 4.00 and I'm in bed trying to sleep. And there's the children playing at the court too. We have a kindergarten in our house, and the kids spend lots of time outside, especially now in the nice spring weather.
I love all the spring signs (both sounds, visions and smells). I wish the weather would never change (at least not get cold and rainy again), and that there could always be spring flowers and buds on the trees. I really shouldn't be sitting here. I'm supposed to study, but I'd rather go out to feel the sun on my cheeks and smell the spring in the air.
