Instead, each partner is interested in what their partner will give them. Falling in love is a huge expectation we have that a partner will magically make us happy. And then that fails to happen, because no relationship can succeed unless it's based on Real Love, where giving is unconditional, without expectations. Look how popular gambling is. Billions of dollars are gambled each year, legally and illegally.
Lotteries exist in dozens of states.
Las Vegas is founded on the promise that we really can get something for nothing. We gamble because we hope that magically we'll be rescued from poverty, loneliness, and anonymity. We adore fairy tales. We love those stories because we all hope for such things in our own lives. For example, we count on the magic of Christmas to make us happy.
