I was at the launch of the UPIS centennial celebrations two weeks ago for a memorable morning.
Next to the principal was Education Undersecretary and former UP dean Dina Ocampo, whose son is in UPIS.
It was a long morning, with performances from the UP Cherubim and UPIS Pep Squad.
UP's students, including those in UPIS, combine formality with freedom, a lot of ad hoc steps, the students quickly recovering if they make mistakes.
I've learned as well through the years to identify UPIS graduates in my classes: They tend to be much more outspoken and articulate, with a calculated recklessness.
