i think im friendly, i talk to random ppl when nessissary, other times i avoid them, depends on the mood and what I have on my agenda. I always feel the pressure of time for some reason, even if im ahead of scedual, so if i have stuff going on i usually dont have 'time' do talk.
OP: indeed, i cannott stand making meeting plans with others, im always the only punctual one. Im always the only 1 to follow the plan, they tend to change the plans, be late or whatever, its kinda bad, but in some ways i see ppl as a hurdle, an obsticle getting in the way of stuff i need to do sometimes.
