You're waiting for a train, a train that will take আপনি far away. আপনি know where আপনি hope this train will take you, but আপনি don't know for sure. But it doesn't matter. How can it not matter to আপনি where the train will take you?
*shrugs* Sometimes the want to get away is just so overwhelming, আপনি don't really give a crap where আপনি go. অথবা rather where the train will take you.
But আপনি don't know where the train will take you,it might stop before circling the globe...which is full of great stretches of water...which no railroad has yet to be built that crosses any sea.
