Hi!
"Love is for the birds" is the name of a song by R. Stevie Moore. The title is a phrase many people use, meaning that humans can't feel love. Also, another common phrase is that it is only money that counts, implying that the only interest in relationships is the profit one can get from it.
I strongly disagree with this way of thinking, because love is not only showed in the relationship between a man and a woman. You can see it in the love of a mother towards her son, you can see it in the love of charitable people towards the neediest, and you can even see it between a man and his dog.
The fact that some relationships are based on interest doesn't change the reality that humans can feel and show love, and money is not the biggest factor in some of them.
Opinion:
A reader could describe reading as a "positive escape" due to various reasons, some including: the reader enjoys it, is passionate about it, feels integrated in it, feels a connection, is an actual escape source from a hard life, etc.
Hope this helps. :)
