A young kid and an old man are riding on a bus.
The young kid asks, "Excuse me, sir, what time is it?"
The old man doesn’t answer.
"Excuse me, sir," the young kid asks again, "what time is it?"
The old man looks up him, but still doesn’t answer.
The young kid is puzzled, "Sir, forgive me for interrupting you all the time, but I really want to know what time it is. Why won’t you answer me?"
The old man turns toward the young kid and says, "Son, the next stop is the last on this route. I don’t know you, so you must be a stranger to this land. If I answer you now, according to my tradition, I must invite you to my home. You’re handsome and I have a beautiful daughter. You would fall in love with her and you’d want to get married. And tell me, why would I want a son-in-law who can’t even afford a watch?"
