I just was rude a few minutes ago, and I'm not pleased to have had to be. But I picked up the phone - had a tough time focusing on the caller ID in a dark room - and heard this minutes-long spiel in English tinged with Indian about something or other. I said "Sorry, I'm not interested," and hung up. But, think:
Some woman - probably someone with a family - someone in a sari needing to make a living - was on the other end of that long, long line, depending on a commission.
I really had to think about car salesmen or insurance salesmen for a while to start feeling better.
Then the feeling-better started wearing off.
