It's like a cheesey movie scene..

You were on the train late one night, it had been pouring raining, and you had only just caught the train. It had been a long day and you were tired - then again when weren't you tired.

You were sat in a seat, your hands in your pockets, trying to avoid anyone and everyone.

You soon fell asleep, your head rested against the window.

James came and sat beside you, not knowing you - but he had to sit there, it was the only seat left. You, being vunerable and asleep.. your head fell against his shoulder.
