When you are inside the elevator with this cute guy and all you can do is stare at the elevator console waiting for your floor number to lit.
When you eat that piece of cake that is not supposed to be yours.
When a friend abruptly pick up that table napkin, skim it to his face when you knew you used that with your runny nose.
When you are in a car with a colleague trying to figure out how to fill the dead air.
When you speak to a guy in a public utility vehicle, thinking he was your old friend back in high school then realized he was not, now you're talking to a look-alike and a total stranger.
When you check your mobile phone even though you know there is no new message or call just to appear you're doing something.
When you tried to make a small talk with your colleague and the question you ask is the most stupid and obvious question not worth asking.
When it's your first day in the office still waiting for your laptop and all you can do is stare at your cube, stare at your colleague's cube and stare as people pass by your cube.
