Look at this swimming pool, which had been left neglected for five years and had become so filthy that no one dared to swim in it. To clean it up, the first thing this person does is remove the thick green algae growing inside the water, as it could make anyone sick. After that, they add some chemicals to the water and use a motor to drain all the dirty water out. After working tirelessly for several hours, filtering and cleaning the pool, you can now see it sparkling clean and ready to swim in. Yet, despite all this hard work, it only received two likes!"
