Input: Text: yesterday i was waiting for a friend at a very busy mall in a large retail district. we called each other to make everything easier and i told her exactly where i was in the mall. after a short while i spotted her amidst the masses and she had a bag of donuts in her hand. although she was walking towards me, she still couldn't see me. without thinking i yelled on the phone: "**hey, i'm here you obese fuck!**"


i then realized that a very fat guy was standing nearby. he turned around very quickly and looked at me with a facial expression i can only describe as pain, sorrow and regret. he looked extremely ashamed and walked off slowly a few seconds later. i was too confused and stunned by the misunderstanding to even apologize. 


i also remembered that a few minutes before the incident, he smiled at me as i was speaking on the phone. i was too absentminded to even register his friendly gesture. 


safe to say that i feel pretty bad.
