A stranger walked into my apartment and sat on my couch

It happened at around 5pm, and I was on vacation, so I had to have dinner before I went to sleep. \u200b \u200b I opened the door and went to the kitchen to get a drink. When I came back, a man was sitting on my couch, and he looked at me. He started talking to me, and I didnt realize it at first because he didnt have his phone. I asked him "what are you doing here?", and he responded "I am here to ask about my rent. I need to know how much rent you have, and to see how much it is because you are not living with me" \u200b I replied "fine" and he left, and I went to sleep. \u200b \u200b When I woke up, I realized that he had left because he was too tired. I tried to call him but he didnt respond. I then went back to the kitchen and took my backpack. I asked him what were his plans and he replied "I am here to ask about rent" and that I should leave. I told him that I didnt need to answer because I had other plans and that I was fine with it, but that I was not interested in his plans and that I was not staying with him. He said "well, I am not staying with you because I need rent" and I responded with "fine" and he left.
