The human being is complex, so much so that they cannot comprehend themselves much less others. To attempt to define one's self or another person is to limit them, placing them in a box and putting a label upon it. We should not seek to limit ourselves.
We can interpret what we can sense and past that we can only assume; assumption is a hazardous method. Would it not be simpler to live transparently? When a person is sad, they should be sad, when they are happy they should show it. Posturing and acting is what will have us all undone.
In the event that a person would find themselves in opposition in what they believe they should accept themselves rather than admonish. In the core of a person is their true path, interest and desires and to deny these is to live in turmoil. We as a people should accept that there is negativity along side positivity. Acceptance of ones self will aid in forward progress towards accepting one's right to be.
Permit yourself to feel and accept that you are what you are and that is ok. Do not over indulge however or give into delusions to hide parts of your true being.
