You were "lucky" to get a ticket to the cinema next to him. Although in reality he was the one who got the ticket next to you at the ticket office after you in line, following you. He chews popcorn loudly, burps, even farts. He thinks you can't hear it because of the loud movie. He farted again and sighed with relief as if something was bothering him. This fool was sitting on your bag strap the whole time without even noticing.

Oh, sorry, I didn't notice hehe...

He scratched the back of his head shyly.
