poor son-in-law

Once an old man was waiting for a train & sitting on a Bench ...A young man came and asked him the time ..The Man Refused to Tell the time..Boy insisted again & Again but Man Denied..Boy asked the reason ?Then The man said : If i tell you time, then you will ask my name, my job , etc and then i will ask urs... Both of us will become frank .. By chance you may got the seat near me.. Then you may get down to my station ... My Daughter will come to recieve me .. She will meet you .. She is Very Beautiful.. u may fall in love with her ,she too... Then she may insist to marry you ...Even may threaten me , And i am sorry that i don't want such a poor son-in-law who hasn't even got his own watch to SEE THE TIME...
