Smile at your enemies.
Being angry has a time and a place, but like lying and love, anger has its own tell. It isn't worth it to gnash your teeth and growl if you can turn your lips up in a smile.
That way they never see you coming.
Peter and I have what I like to think of as a working relationship. Not your average working relationship, however. You have to understand what I think of as work. Work isn't just what I do for the FBI or a good hustle. Anytime I have to save face in front of someone, I consider it work and the amount I have to do that around someone denotes the type of relationship.
For example, if I were hypothetically trying to initiate contact with a mark, I'm not going to tip them my cards in any situation. But for someone like Alex, who I've known for some time, I can let loose most of the time, except when it comes to information about a job or anything I may value, but I can be angry with her. Now a mark is a mark, but Alex, who I still play it close to the chest sometimes with, is a friend.
With Peter, I can be myself, but only until it comes to my personal history or relationships. If I let any of that go, I could wind up in prison for life or lose any future leverage I may have.
The worst part of our working relationship is that sometimes I can't help but look at him, with his perfect wife and his perfect dog in their perfect home, and I see the man that ruined my life, and possibly any future I may have ever had with the woman I love.
Loved.
Sometimes I just hate him.
But I just smile.
