sitting in my room, doing nothing for 2min., I heard many thigs:
a chirp by a bird
a wind-bell ringing
cars and bikes passing the road near my house
sound of my computer making
plane probably passing the sky near my house
I did not imagine that there are that many sounds.
Also, I noticed that i am usig energy even though I'm not using them...
I don't usually listen to music while walking, so I hear many interesting sounds ^^
I suggest you to stop listening to music on the way to school and listen to the nature one day*
I guess you can fnd something new :)
