The reason I caught the train is because I drank my milk straight from the carton. The four seconds for a cup would have meant the difference between slipping in neatly or the doors closing in front of me.

If I sit really still and don't go to the restroom, I will be invisible. Jack will not see me passing and ask about my overdue task.

Here is my trick: walk my regular striding pace and pick out the nearest male at the same speed or more. He is my objective and I will trail him for blocks until I take over, victorious. If he figures out what I am doing he will get extra points; if he turns or disappears before I catch up I lose.
