Ganun ba? It seems you are a little bit older than me..
My Plaridel experience was a great one even though I only stayed there for a year.. I was graduating when I joined.. I loved writing articles in Filipino during my college years.. I just browsed through some of my articles yesterday and it gave me goosebumps.. Whoa!!! That was 13 years ago.. Nostalgia!!!
Like you, I also joined the Plaridel in my senior year. I wrote for the La Sallian quite a bit longer (2+ years).
I am noticing that current students and/or more recent graduates now call themselves La Sallians when way back, La Sallian was termed for the school paper while the students were called La Sallites. Just a bit of "historic" trivia although hindi gaano malayo ang stay ko from yours given the number of years you mentioned.
