Koee hotaa jis ko apanaa, hum apanaa kah lete yaaro
Paas naheen to door hee hotaa, lekeen koee meraa apanaa

I do sincerely feel that when Gulzar wrote this song he did not know what long
distance relationships were al about. Had he known, he would never have said
"paas nahin to door hee hota", because no matter what one thinks of long
distance relationships in the beginning, eventually it gets tough to keep up.
