Common sense is...

• when a bus door is opened again by a bus driver for latecomers after it had been closed one second before. This always makes me smile. A driver who turns a blind eye to take off is like a robot being controlled by timetables - lack of human common sense.

• when you see somebody grabs their bag, ready to get out of the bus and you keep out of their way or c'mon why can't you sit inside by the window so when someone who just get on a bus doesn't have to squeeze themselves in that narrow way (because of your knees, feet, and shopping bags) to the inside seat. Do it at your living room.

• when you know you're supposed to call me now!

• and the common sense award goes to a manager at Kyoto restaurant in SOHO. A service with common sense to details.
