hmmm.....
English question! (o_o)
should I use the word talk or speak in my sentence i wrote?

Speak is what is generally used, but there's nothing really wrong with talk.

It seems the "leave a gap" strategy is common across many places - I see people often doing it in lecture theatres, buses etc.  I guess sitting next to someone when there's free spaces elsewhere infers that you have some interest with them.  Otherwise, it gives you more free space :P
