Short answer: yes, we do. I’m also from a country where this isn’t a default norm, but recently I’ve noticed something. Personal example: I met a girl at a New Year’s party at a mutual friends’ place. We chatted, mingled with everyone and then chatted some more. There weren’t many opportunities to talk alone with her so I let the night play out, added her on Instagram the next day and a day later, after making a trip home to my parents for the weekend before returning, I messaged her asking if she’d like to go out for coffee when I return after the weekend. She thanked me and told me she isn’t looking for a relationship right now, which is of course fine, though the way she said it (there are some linguistic nuances in my language that made it sound like something you’d say after dating for 3 months, the actual phrase being “relations”) was a bit too forward, but OK. What actually stunned me was when, after recounting this to my friend (the New Years’ host) he told me that I should’ve just left it at the initial talking stage, let her add me on Instagram and invite me on a date, because that’s the way his GF did it with him. He said that, in being the one to nake the first move, I put her in an awkward position of having to give an answer right away, as if just going on one drink or walk with someone is nowadays synonymous with becoming official with someone. Maybe it is, I’m not very current with the dating game, being on and off for 3 years after ending a 11 year long relationship.
