If you are a fan of Friends then you know how neurotic Monica is about having everything perfect. She cleans things that are used to clean other things. She has to have everything just the right way. As you can see you start to understand why her friends are often driven to extremes.
Why does she have to have that type of control? Yeah she maybe a bit OCD but often you see this type from people who are fearful of being seen as a fraud.
So why am I showing a video about Monica? Because we as people see this all around us and we can laugh at the case of perfection we see in Monica.
