However, a NUDGE or a bump...he invaded your personal space and he's accountable for that. You should have looked him straight at his face and stood your ground....THEN REPORT HIM to the authorities. Maybe (in my point of view), you should have reported him (like the rest of us are saying) and tell us the aftermath. Ranting here...yup, you vented out...but that didn't resolve this. But hey. I'm just stating a view, mine ;P
