A man pulling out of his driveway this morning was taking his time, and eventually a car approached and had to wait while the man finished backing up. I was walking by and heard an apologetic "Sorry" come from the man to the waiting car. Problem was, while his window was open, the car's windows were rolled up and couldn't hear his nice apology.
I continued on my way to work, and eventually had to wait for a gap in two lanes of traffic to cross. While waiting, a car in one of the lanes honked at me, saying I could cross in front of him. Problem was, there were cars zooming past him in the other lane that surely would have struck me and the other pedestrian. I proceeded to tell him this, while motioning for him to continue moving. He didn't have his window open either.
Do we say things to out loud, stuff that nobody has a chance of hear, to make ourselves feel better? Does this mean trees really do make a sound in the forest?
