When a man walks by his girlfriend on the inside of the sidewalk while making her walk closest to the road, that way if there's any danger she can take the damage leaving the man to escape unharmed. It's human nature.
Reverse sidewalk rule? Nah man, fuck that she can walk closest to the street, I ain't about to take on a moving car.... I'm not about that life, bitches are replaceable, I'm not.
