person B: What did he want?  It's kinda scary when that happens_comma_ you never know what they want.
person A: I was scared at first and then he hollered and pointed to the top of my car and I had left my purse on it. Boy_comma_ did my face get red. 
person B: Well a good samaritan after all!  I'm sure you were embarrassed_comma_ but also glad that you didn't lose your purse!
