I’D like to share with readers this rather provocative e-mail from business columnist Oscar P. Lagman, Jr., asking me to comment on the frequent use nowadays of the phrase “on the ground” by personalities in the news. He thinks that their overuse of the idiom is “inappropriate,” saying that it reminds him of my oft-said comment in my columns that “at the end of the day” is annoyingly overused by media and government officials.
