If a Parisianer does not make eye contact with you, then whatever wrong they have just committed doesn't count.
Want to test the theory?
Rent a car and drive in Paris.
In the States, if you need to change lanes, you put the blinker on and then merge. If there is heavy traffic you may in fact roll down your window, signal that you would like to merge in front of them and then offer a friendly wave of thanks.
However, if you are in Paris, they make no eye contact whatsoever and move over. If they have just cut you off and are now stuck in front of multiple lanes of traffic that can't pass them, including you, they just look straight ahead. Horns blaring they pay no attention, they just look straight ahead. I have never seen grown adults do such in my life! Sometimes I play by the rules (when I'm by myself) and other times I roll down the back window and allow Aidan to wave us in the lane that we need with sister Jaylee throwing a wave of thanks up for good measure.
In the car, this is met with a smile in the rear view mirror, in person the children are looked at as simply an obstacle or a source of distraction as they make their move.
Today after school the kids and I ran into Monoprix, this my friends is NEVER a good time to take children to the store in Paris, but I did it.
At the check out I notice a Granny looking very disgusted at the massive lines as she shuffles from line to line to see who has the least amount of purchases. Please note, there is a line especially for the elderly and handicap, but apparently they find it completely offensive to have a line all to themselves, so they torture the rest of us. There is also a line of 10 or less items, but that's overrated too.
So Granny, most likely 75-79, is shuffling from line to line in her hot pink suede kitten heels complete with back seam sheer black stockings. As she passes me I turn to get a bag and then the next thing I know I look up and kitten heel wearing Granny is in FRONT of my cart! I ask Jaylee if she saw her do it.
Jaylee says, "Yes, mom, but you're not supposed to say that out loud!"
Granny, is not turning and now she is making small talk with the lady in front of her and neither of them are looking at me. I am staring a hole in the back of her head. At this point I push the cart closer to her and mind you Aidan is inside the cart just biting at the bit to unload the goods. She still makes not a flinch to turn around with English yelling, cowboy boot wearing Aidan on her neck.
Now she is at the end of the counter bagging her purchase and smiling at the cashier and making NO eye contact. Not a small wavier of apology or thank you for not calling her out in front of the entire store (reason #181 I wish my French was better, because I would have tapped her on the shoulder and told her it would be my pleasure for her to cut in line and please enjoy the rest of your day, of course all said with a devilish smile).
But, no, nothing was said, just the classic game of, "If I don't look, it doesn't count".
