As a child tears away the wrapping paper, they are filled with excitement to begin playing with their new gift—that is, until they consider the gift another child received to be better than their own! Suddenly, this new gift that only minutes earlier brought excitement now feels like a disappointment. When we compare what we have to what we wish we had, we can quickly become jealous and lust for someone else’s possession.
