When a person admires their own attributes in a egotistical way its narcissism, 
I didn't know that!  I do know some people with big egos though!
Its actually considered a personality disorder by the American Psychiatric Association
Really?  I had no idea!  I thought they were just really conceited!  Is narcissism common?
Sigmind Freud wrote about it in 1914
I've heard of him!  He has quite the reputation!  1914?  So it's been known for a long time.
Narcissism is also a social problem as you can imagine
