person A: A month or two ago my girlfriend randomly broke up with me and I had no idea that she was even close to considering that.
person B: I am very sorry to hear that_comma_ that must be terrible....
person A: It wasn't a great time_comma_ but it just really irked me since I had no idea that she was not into me at that time. She must've been really good at faking it.
person B: I undertand that. People are crazy like that_comma_ I never understood it
