Would you say something?
When my boyfriend attacked me, I screamed as loudly as humanly possible knowing all of the windows were wide open. No one knocked on our door or even called the police. When I went outside and was talking to the police on the phone, my neighbors came out to do 'stuff. They fiddled around with 'stuff' (gawking at the car accident syndrome,) but not a single one would look at me let alone ask me if I was ok.
