or simply ostentatious. Give Rui a break. IMO, Rui's english is quite impressive. After all, it is not his native language. His etiquette faux pas is not going to ruin his image as a young ambitious and dedicated reporter. Admittedly, his self-righteous mindset, however, can be a concern. Still no need to beat a dead horse.
Whatever Rui did could only reflect himself, nothing more and nothing less. Anyone suggesting more than this is overestimating his caliber.
