person A: I cheated on my math test today. Feels bad_comma_ man.
person B: I can understand that - I think all of us_comma_ at one point or another_comma_ did something we were ashamed of.  
person A: I know...I'm not sure if I will ever be able to sleep again.
person B: I know that feeling_comma_ kinda sick to your stomach can't get it out of your head kinda thing.  We all have to have a method to overcome it and move on.
