To practice means that you do something you can do in order to do something that you can't. For example, if I decided I wanted to run a marathon, I would know that despite my best intentions I can't run 42 kilometers but I can run, if I was determined, maybe 1 km.
The subject of immigration engenders contentious debate, complex discussion, and conniving diatribe among Americans. Four years ago, the mother of a recently elected Republican senator implored her son to be compassionate in his legislative work on the issue. She reminded him of their own family’s journey from central Cuba to south Florida and noted that undocumented immigrants—she called them los pobrecitos, “poor things”—are human beings seeking dignity, work, and a better future just like they were.
One wonders if Marco Rubio remembers his mother’s message.
