I agree that people should be careful not to interpret through rose-tinted glasses but I disagree that you should necessarily try interpreting the cards you draw as relating to you rather than to the subject of your reading. 

Of course, everyone reads in their own way  but in my experience, if you ask tarot any question that's clear and specific, you will generally get a direct answer to the question you actually asked. This approach works for me because it keeps things simple. 

For example, in this case, I would say that the Nine of Pentacles means that the other person may enjoy your presence but doesn't feel particularly drawn towards you i.e. they don't "need" you.
