Have you ever played with a rain drop at the window seat of a train? Moisture will embrace the window bars as a thin coat. A pristine tiny drop takes the initiative and starts to move a horizontal path along the bar. On its way it accumulates more wetness and grows in weight till it reaches a tipping point. And you observe all this drama unfolding with an outstretched palm waiting for the drop to gently bless you with a touch. The trick is in judging where the drop decides to fall and being there just at the right time and the right spot to receive it. Just like love! The iron bar of the window is time. Love, like the rain drop, gathers momentum as it travels along time and at some tipping point it decides to burst and reach out. If there is an outstretched palm waiting for the fall just at the right time, magic happens!
It's been a while and it is about time this happens. They simply did not know who should play the role of the drop and who should wait at the window seat. Somehow they both preferred the window seat. Enough signs were exchanged often that the palm is outstretched and waiting. May be they were just waiting for the rain.
