Because of evaporation .

Kyun jhoome hain gagan,

Because of earth's rotation.

Kyun machalta hain mann,

Because of disorder in digestion.

Na Tum Jano Na Hum!!!

Kyun gum hain har disha,

Because u have poor sense of direction.

Kyun hota hain nasha,

Because of drug addiction.

Kyun aata hain mazaa,

Because u enjoy the situation.

Na Tum Jano Na Hum!!!

Kyun aati hain bahar,

Because of change in season.

Kyun hota hain karar,

Because of taking tension.

Kyun hota hain pyaar,

Because of opposite attraction.

Na Tum Jano Na Hum!!!*
