Can madame be used in a flirting context ?
I have a male colleague (early 30s, I'm late 20s) who always refers to me as "madame" — in person and in writing. But with our other female colleagues, he uses their first name. We've also had a few tense, flirtatious moments between us. I can't figure out what to make of the "madame" thing — is this a technique de drague (flirting move)? In English, a guy who always calls a woman "miss" instead of her name can come across as flirtatious/teasing. Is "madame" the French equivalent, or am I overthinking this?
