quick story from when i was a kid:
Everytime we stopped at a red light, my mom would "predict" when the light would change to green. Little did i know that she was counting down from when the opposite lights turned yellow.
So everytime we stopped she would tell us when to count down from 5. and everytime, she was right. I thought my mom was magic until i figured out her trick, but to this day i think about her everytime i hit a red light.
