Michael closed the door and knew at that moment [and instantly knew] that he had made a mistake. He had been summoned for to a meeting with his boss, called named John the day before. In During the meeting they had an rough argument, and consequently [as a consequence] Michael was fired. 
     He Michael was feeling really sad, so he decided to go for a drink. He was sitting alone when a beautiful blonde told him asked "May I have a drink with you?". He said to her that it "That would be amazing," he replied, and they started a nice conversation.
     They drank too much, alcohol so they were a little drunk. She kissed him. "Would you like to come with me to my flat?," she said asked. Michael accepted her invitation. 
     in that moment, John did not remember his boss After arriving at her apartment, the last thing on Michael's mind was his ex-boss, but he noticed that but in her apartment there were three photographs of him on her dresser. John's photos "Who is the man in these pictures?" Peter said Michael asked. "He is my husband, but he is not here [home], and I expect suspect that you do not mind that I am married." Michael cracked a sly smile and said to himself: It were going to be a "Revenge is sweet!" 

Another amusing story by Aureli. Consider not using the adjectives to describe emotions and nouns such as "rough argument" and "really sad." Arguments are supposed to be rough, and the difference between "really sad" and "sad" is not necessary. Phrases such as "In that moment," although correct, are awkward in English. Writing is best accomplished concisely [concisamente]. Great job, and keep it up!
