…There’s no such thing. I don’t think so.
Everything that makes a person happy is not happiness in themselves but they trigger something within that person to make him happy. They trigger memories, quench needs, satisfy wants. And whatever it is, it makes a person complete and so it is never shallow. It makes a person happy and therefore it is something deep.
*Random thought after my roommate gave me some biscuits and I felt really, really happy.
