This may also be rather an explanation than a translation. It's interesting that dictionaries translate не становись в позу as "don't give me attitude" or "stop attitudinizing", but I don't think they would fit in there.

Literally translated бессмысленно - pointless, неконструктивно - not constructive

Tanya as usual you are my saviour 😊

Dave, i'm still wondering whether there's a more accurate option for that не становись в позу. The point is it means a kind of behavior when someone isn't just stubborn, they are obstinate because of true o fake feeling of offence.

it s from a russian series )

As usual my question was about your version of that.

Tatiana; neither worthwhile NOR helpful. Although I would say: it's not worthwhile and doesn't help matters.

Yes, I spotted that OR but I was probably too lazy to correct my mistake then and later I somehow forgot about it. Sorry, guys. ;(
Uly, there should be your version. ;)
