The Davis Square Community

I saw a couple arguing in that vicinity yesterday at around 1:15/1:20 pm. Young, probably early 20s at most. He was average height, skinny and wore a baseball hat. I was across the street and they were behind me so I didn't really see his face. I was worried and wondered if I should call the police--she kept telling him to get away from her. If the timing is right and that would be the same couple? But I can't say more than this, really.
