Was getting into my car next to a woman who was walking to her car with her husband/partner and approx 4yo daughter (presumably), and heard the her having a real go at her DD. Thought nothing of it as it is not unusual for me to have words with my 4yo DD about poor shopping behaviour!
Then they all started getting into the car next to me and I heard the following:
Mother: 'Get into the car you fucking little retard.'
And then shouted at her husband 'Did you see that? She caught my fucking finger in the door, stupid fucking bitch!.'
Door then slammed shut and I could just hear muffled shouting.
I just sat there worrying about what to do, and whether the little girl was ok and then ended up driving off. The people looked quite menacing IYSWIM, and I was worried at the time that if I confronted them they might get violent and I had DD and DS with me.
However, once I drove off I felt terrible, and stupidly hadn't had the presence of mind to take a number plate.
Can't stop thinking about that poor little girl. What would you have done? I feel terrible.
