7 years ago when I lived in Puerto Vallarta, across the golf course in an apartment at the very first level, we can just walk to the lake that was in front of our terrace. So one day after school I saw my mom with a weird scary face and I was just staring at her wondering what was happening. My sister and I enter to the car and my mom just start to drive and telling us that tonight we were going to sleep in a hotel because a group of men were going to fumigate our house and that we couldn’t be there because the smell was toxic, so I stop asking questions and I just enjoy the night in the hotel. The next day after school we went home and everything was normal again instead of the smell, it was still there, but we really don’t care we just sit down for eat. My mom was normal again, so she decided to tell us the true about the weird night of the hotel; she told us that a crocodile was under the sofa and that it was huge and he just stay there and anybody can move it, my mom really was freak out she was so scare, she almost call the police, but then my that just call the staff man that worked in the hotel so they can take him out and left him in the lake again. I was shock I really get freak out to. That night, when I went to bed I really couldn’t sleep, I couldn’t sleep for a week I just feel the croc was under my bed. Eventually I get over it and just forget about that. A month later we heard about this old lady that always went with her puppy to the golf course to play with us and told us that her puppy had been bitten by a crocodile on his leg and that the puppy would never goanna walk well again, and after that we saw the puppy just walking all wrong and crying every time he walk. Every Sundays my family and I went to play golf and we always saw this old lady with his bitten puppy just seating on the golf course restaurant.
