A look in the mirror

In my natural state, eleven of these points apply to me. Making friends has become much easier, but I have developed coping mechanisms for dealing with or masking some of the others. I am trying very hard to make sense of my life. Underneath the jollity of my everyday life, I am actually a very serious person, and I never stop thinking, analysing and processing.
Last night I received an email from a friend which upset me. I don't understand why he said what he did.
