I get a similar little lift when I see a furniture delivery truck. It's just the knowledge that someone, somewhere is about to be very happy. Someone is about to open their door to their new couch, TV, refrigerator, or whatever. Earlier today I heard a rumble outside and glanced out the window to see this:
IT WAS SOMEONE'S HAPPY DAY! YEA FOR A NEIGHBOR!
And later today, there should be a similar truck at my house. Pictures and details to come!
