Strange experience

Yesterday I was on my way across the river Suvansiri on ferry(machine boat) where I had a seat near a foreign tourist aged person above 60 years approx (European ). I was eager to talk with him as I have never met a foreigner from so close. I asked where he came from. Then he asked me why do I ask, and why should he let me know , at which I was disappointed. I decided that I shall never ever talk to a foreigner whether he be a tourist or a guest.
