In "The taxi driver's daughter," Mac giving a free ride to a priest could be seen as his way of showing kindness and generosity, rather than a direct investment in religious beliefs. However, the author's use of the phrase "investment in Jesus that pays" does suggest a sense of irony towards religious issues. It implies that Mac may be hoping for some sort of reward or favor in return for his good deed, rather than simply doing it out of the goodness of his heart.

One instance of bird imagery in the text is when Mac describes his daughter as having "feathers" in her hair. This imagery could symbolize freedom, lightness, and a sense of flight or escape. It adds a whimsical and poetic element to the description of the daughter, highlighting her unique and free-spirited nature.
