"Can I ask a couple of questions?"
Translation:Posso chiedere un paio di domande?
So does that me that coppia is more for relationship couples (exactly 2) and paio means more like a few (of non matched) things. IN English, the latter context may not be exactly two, eg I went out with a couple of friends- could be 2 or 3 or even 4. Is that the correct usage in Italian?
