Well no wonder Marie's confused (as well as anyone with an X chromosome)! Here's how a woman interprets this:
He stops her on the roadside, she smiles and is polite because a "nice girl" doesn't create drama or cause distress. Only trashy girls do that.
She's thinking:
a. He's grown tired of bimbo b. He's looking to re-connect c. He's flirting to get back in her good graces d. He's ready to dump bimbo and re-commit to her
Hello! We are NOT on the same page, Allen!
So you're saying Marie should:
1. Be business-like instead of nice 2. Keep conversations short and un-personal 3. NEVER let him think things are ok by smiling and being congenial
...is that right?
So chuck the nice manners and do a little ball-busting instead?
