1 You find yourself drinking lukewarm black coffee out of a big bowl in the morning.
2 If someone refers to you by a pronoun (he, him, she, her) rather than your name, in company, you consider that to be grounds for ending a friendship.
3 You chill the glasses as well as the champagne.
4 You panic if the boulangerie has run out of bread.
5 You prefer proactive aggression – an angry shrug, maybe some shouting, swearing and arm waving and then... poof, all forgotten – to the passive kind.
