A lot of people you work with have noticed that many random things which they own are going missing.
While driving with your friends to a party, you are carefully paying attention to the street signs as directions are being given to you by your passenger-seat companion.
It sounds really bad. You are on an airplane and after you have taken off for a 4-hour flight, a baby sitting right behind your seat starts to cry.
You are playing the card game hearts, and your partner is demonstrably less skilled and experienced than you.
You are at a party where you strike up a great conversation with someone you had never met before.
