Poor Son in law

Once an Old Man was waiting for a Train sitting at a bench... 

A Young Boy came 2 him & asked the time...
Old man refused to tell the time.

Boy insisted again and again but the Old man kept denying.
Boy asked for a reason.

Old man says :- if i tell u the time, 
then u will ask about my Name, Job, etc... 
Then i will ask about you... both of us will be frank... 
By chance u may get a sit with me. 
Then u might get down at my station..
my Daughter will come 2 receive me, she will meet you... 
she is Beautiful. you may fall in love with her, she too. 
Then u might decide 2 get married & I am sorry, 
i don't want such a Poor Son in law, 
who doesn't even have his own watch to see the time!!
