person A: This lady at the store was yelling and hitting her toddler the other day when I was shopping. I was appalled at what she did.
person B: Wow_comma_ no parent should ever abuse their children like that. Did you or anyone do anything?
person A: I wanted to_comma_ but didn't know what my place would be in that scenario.  It was quite maddening and off putting.  
person B: Yea I totally understand where you're coming from. Hopefully someone nearby was able to call CPS or law enforcement.
