Of LOVE and LUST

What is LOVE? What is LUST? Like Mr Andrew wrote in his blog-'Intercourse on intercourse', where do we draw a line btw ilust and love; and how does sex come into play in the two cases?

Love waits. Lust wants.

Love can’t wait to give what’s true and honourable. Lust can’t wait to take.

Love mends. Lust hurts.

Love is secure. Lust is selfish.

Lust ends. Love lasts.

You gotta be kidding me if u believe I am so philoshical. NOPE, i am not good in this. These lines are borrowed without permission *smiles sheepishly* from Joe White.
People, take time to think about it okiez?

I guess love is more like undersstandin, tolerance n being compatible with THE ONE; it grows with time, with nurturing from mutual parties. There are times when you all are too busy for each other, yet you do know that u2 can count on each other.
Lust is an infatuation kinda thingy, don't u think? You wanna see THE ONE everyday, you gets nervous when u see him, ur systolic BP and dystolic BP is no longer 110/70 mm Hg (or withing that normal range), you think of his looks now n then. You can't really be urself in front of him, you wanna impress him-so u can't even be ur seilly self in front of him.
(p/S: For guys, think vice-versa, ok?)

So how does one tell if the other party is interested in another? Mens are from Mars and Women are from Venus; hmm, so they said. So call I call upon Mr. Mars and Miss Venuses tp shed some light on this matter?
