Appearances are deceptive. Some people pretend that they are happy, friendly and straightforward, but in reality they have a secret dark agenda. They love their big smiles but are completely unaware of their negative and egoistic plotting. They have a perfect cover. So, stay away from very positive, loving and friendly people. You will never know what they are after. It is so much easier to deal with assholes, because then you know for sure that what you see is what you get.
The desire for food is inborn. We want something to eat if we are hungry. But eating can turn into a disease. Some people just can’t stop eating. They eat and eat till they end up in hospital.
Egoism is also inborn, I believe, and egoism can also turn into a disease. Some people just want more and more, but they don’t end up in hospitals or addiction clinics.
