There you are, in line at the grocery store when a very attractive person brushes up against you accidentally…or so you think. How can you be sure? You can’t right away, so you look again and try and make eye contact this time. First, to see if what you thought you saw was an attractive person, and then next (if you still think so), to see if the brush might have been deliberate. But how can you tell with a look? Maybe they were off-balance, or the person behind them bumped into them, or maybe they are nearsighted and left their glasses in the car. Before you make another move, I know you realize a lot is at stake here; what you do (or don’t do) in the next 30 seconds could change your life…forever.
