bedroom window

I have my bedroom window open at night so I can hear the wind through the trees and the trains and the fog horns. I also hear the birds in the morning when they first chirp - early around here - lately about 5am. As much as I love birds and all their pretty sounds, it's the one downfall of an open window. Somehow the night noise feels more relaxing, it's a deeper sound, closer to the heartbeat - morning noise quite the opposite, more high pitched, more intense. Maybe it's my state of mind too? I wish there was more calm in the early hours, but life feels so rushed and anticipated at the beginning of the day, like there's always a thing to do. But at night - the day's all over, there's nothing left to do but sleep. Oh, and how I love to sleep.
