Facebook part 2

Anyway, the old man asked someone else what this 'facebook' was all about, and was greatly enlightened. He asked the 'boy' if he was on facebook and promptly informed his niece that the answer was yes.

Now the 'boy' had a fairly common name, like Ajay Kumar (not his real name), so when the niece went hunting on facebook, she found about a hundred people. So she asked her uncle what shirt the 'boy' was wearing on facebook.

The answer was duly conveyed back: a striped shirt.

Next day, the niece was back. There were 20 Ajay Kumars with striped shirts. "Ask him," she said, "whether the stripes are wide or narrow."

The search is still on, far as I know.
