person A: I was walking home one time and a really big dog came charging out from a house at me barking really loudly.
person B: Sometimes dogs just bark a lot. Did anything happen?
person A: Thankfully not really_comma_ it stopped near me and barked a lot until someone got it_comma_ but it was really frightening until it was retrieved.
person B: Thank goodness. I'd be scared_comma_ too. You can't really know whether a dog is harmless or not sometimes.
