The Rudimentary Difference...
I received a forwarded mail few days back which explains the differences in an apt fashion through a series of situations...

When a BOY......
When a BOY is quiet
He has nothing to say....

When a BOY looks at u with eyes full of questions,
He is really confused....

When a BOY answers "I M FINE" after a few seconds,
He is actually fine....

When a BOY stares at you,
He is either amazed or angry....

When a BOY lays in your lap,
he is wishing for you to be his forever....

When a BOY calls you everyday,
He is spending a lot of time to get your attention....

When A BOY sms's you everyday,
He is forwarding them....

When a BOY says "I LOVE YOU",
It's not the first time....

When a BOY says that he can't live without you,
He has made up his mind that you are his for at least a week.

When a GIRL.....

When a GIRL is quiet,
Millions of thoughts are running in her mind....

When a GIRL looks at you with eyes full of questions,
She is wondering how long will you be around....

When a GIRL answers " I M FINE" after a few seconds,
She is not at all fine....

When a GIRL stares at you,
She is wondering why are you lying....

When a GIRL lays on your chest,
She is wishing for you to be her's forever....

When a GIRL calls you everyday,
She is seeking for your attention....

When a GIRL sms's you everyday,
She wants you to reply at least once....

When a GIRL says, " I LOVE YOU",
She means it....

When a GIRL says, " I MISS YOU",
No one in this world can miss you more than her....
