As a human you need to have people around you who care, right? People who check on you and ask you "How are you?" out of genuine concern, not politeness. People who love you, even if it's only your mom. People you love back.
Humans need that, right? Beyond water, food and shelter, isn't that basically the most important thing to have?
Me? I have no one. My life is utterly empty.
Yes, there is a cat and an another human in my flat, but neither are capable of empathy or mature conversation.
