I'd never count on anyone saving me, regardless of where I was. Nonetheless, I really hate to think that we can bring all of humanity's behavior down to one person's experience. No matter how well documented (and obviously terrible). Just to restore, however small, your faith in humanity... just last week, my BF, changing back into clothes at 3 am, went to check on the safety of a neighbor we don't even know in the midst of a domestic disturbance where we'd just heard a lot of yelling and then what sounded like someone being thrown against a wall. Scary? Yes. Dangerous? Definitely. But nonetheless, yes, a total stranger went to help, in the middle of the night, in the city. Without hesitation.
It happens.
