Walk to S-11

"S-12 is so far, its just S-2 now. Throw in a couple of AC coaches, that's one helluva walk. Also why dont they make the platforms more even, can't even pull my strollies here". These thoughts were immediately quietened as I saw a beautiful 22ish girl guide three 80ish oldies and tell them "Our coach is S-11". As we reached S-6, the girl said with a moan "Thatha, my legs are aching. Wonder why they can't even make the platforms even". The old man replied with a maturity that comes with age “Let me carry the bag, little one".
