Does it matter whom the speaker, if the words are genuine?

Names are associated with power (or lack thereof) and the absence of such could increase the sincerity of the words. If you think highly of 'xyz' but the opposite of 'abc' -- does this affect the influence the words have over you? Are you more likely to take abc's phrase with a grain of salt? The expectancy of certain words from certain people ultimately compromises the heartfelt thoughts of others.

Some find appreciation in making others feel good without wanting a thank-you.
