My non-fiction creative writing assignment

Maybe I should call the police, I thought, but then a loud thud jerked me forward. Silence prevailed in the bus. Even the angry words of the man sitting behind me had stopped. He had been verbally abusing his girlfriend (or wife?) from Sham Shui Po to Tsuen Wan, where the bus was standing now. He annoyed me, but the submissive, quiet and appeasing tone of his partner annoyed me even more. Why did she let him treat her like a doormat? Why couldn’t people leave an abusive relationship? But life is messy. I’ve come to realize this messiness a year after this bus incident. When I have this woman in my mind, I can see myself in her.
