Ittefaq se mile is dost ko kabhi door na hone dijiyega,
ki jaam hai yeh.. saaki se kabhi door na ise kijiyega.
Aapki muskurahat ka hi hua tha main kayal,
aap bus yuhin sada muskurate rahiyega.
Aur jab na ho wajah muskurane ki zindagi mein koi,
to hamare saath bitaye kuch pal hi yaad kar lijiyega.

This one was initiated on a chat session with my sis.. my friend.. long time back. I said the first line (I modified it a little).. and she came up with the second. Since then.. it was just sitting on my desktop and it took me quite a while to come up with something to complete it.
