The relationships a narcissist has in his or her life are shallow and sick and twisted. Perhaps they have more relationships but they are not good quality relationships and the same level of intimacy is not there. Narcissists don't like intimacy (sharing emotions and personal private thoughts), if you try to get intimate with them they might even give you a look which says "don't even think about it"
Dont offer them intimacy, that's too human (weak) for them.

Anyone could do either - in the view of many narcissists everyone else is there to flatter and supply them with what they need emotionally. You can go from being overvalued if you are doing this 'pumping up' to being apparently hated and put down viciously (often behind your back too) as soon as you don't do what they feel you should be doing.
They abandon them, often in a cruel and heartless manner. To see you suffer gives them an added thrill.
Word relationships that often appear in standardized tests and ask you to find relationships and often pairs are known as analogies.

A scatterplot is the best tool. Regression or correlation can often fail to find non-linear relationships.
