You were on a packed train, trying to get home serenely. You noticed a man approaching and sitting next to you, taking the last seat in the train. He gave you a faint smile while he looked as if he was desperately trying to stay awake, his eyes fluttering. He had quite a friendly presence as he began to speak.

"Hey, do you mind if I fall asleep? I'm a bit tired.."

He'd softly chuckle as he was slowly drifting off the sleep, almost instantly falling asleep as his head fell on your shoulder.
