ты идёшь куда-нибудь в следующую пятницу?
Ты собираешься куда-нибудь пойти в эту пятницу?
I asked my Russian friend how to say "What are you doing this friday" and after receiving the first example I said "ah it's weird to me that you use the present test to ask something about the future" to which she sent me the 2nd sentence.
I now realise we do actually say "What are you doing on friday" which is the present talking about the future however I was just wondering if there was any fundemental difference between these two sentences or are they 100% interchangeable?
I am aware the perfective normally denotes something that is to be completed so is the first more general, about regular pub or bar visits whereas the second is more about a specific activity to plan and do together? I am just putting it out there so people get what I am asking about.
Thanks, Jake
