I asked someone to stop saying “half 5” as a time since it was ambiguous & confusing, especially given that we weren’t in an English-speaking country & folks come from all over (many culture this means one thing or the other, while many—including where I grew up—don’t even use it as an expression). I asked a few times, then another time we were gonna meet up, I asked him “half five ha” “so what time do you really mean?” “half 5” …so I just didn’t show up, wasn’t in the mood. We haven’t really talked since.
Eastern countries don’t build all their communal events around booze but instead food. One of the many reasons I have no interest in moving back to the West.
