Bus creep

I was sitting on the bus on the inside seat when the man across the isle starts leaning away from his seat and slowly but progressively moving into the seat next to me. I’m uncomfortable he’s getting into my space and suddenly his face is near my face I think he’s either trying to smell me or kiss me. I think I’m trying to get away and people around me a trying to remove him from my space but he keeps getting closer. He’s balding kinda a ben Franklin hairstyle.
