Spread Your Love: Last day of High school

Last day of High school

"These are the best days of our life"

We grew up watching movies and TV shows and reading books that made high school out to be such fantasy. Hang-out and having food trip with our friends. Watching your batch mates and crush playing basketball game and supporting them in every competition.

My footsteps echoed in the empty halls. Already I could feel the change in the school, even though classes had only let out a week ago and finals were still going on. It was as if the very walls had exhaled their last breath. The classrooms were equally still. The wide-open doors could have been waiting for entering students , like any other day. The boards showing those names who have incomplete requirements in each subjects.

I'd come back for one last walk around the place that had practically my home for the past nine years . I found my feet carrying me faster up to the second floor and fourth floor around the halls as i peered into the classrooms that had been mine. I felt myself looking closure , for some sign that it was really over , but all I could think of was the memories.
Everywhere I looked , they surrounded me. The stage , where I had performed so many times with my classmates , my locker , the trophies near the gate 1 , our OHP where all of the students used it as a mirror and our high school building.

As i looked at my watch -- 3:34 pm The time that for 9 years in this school had signaled the end of my day. I realized with the start that this time on Monday , I would be sitting at my own graduation ceremony

I would be wearing , not simply starring at my gala uniform and black shoes.
My feet took me to the ground floor and I sat down in front of my computer and rubbed my eyes , suddenly tired. --What was it nagging at the back of my mind? What hadn't I done yet that wanted to , that I needed to , before I said goodbye?

----

What had high school had been for me?

It had been pride gut - wrenching laughter and exhausting tears. It had been hugs that said more than words and classes raucous with enthusiasm. It had been people. True all of the above had taken place here but this was really just the shell that had housed the pulsing life. I had lives for 9 years THE PEOPLE I WOULD SEE TOMORROW, THE MEMORIES WOULD ALWAYS BE MINE . IT WAS TIME TO GO.

Isang Realidad : Tinig Ng Pagsulat

Isa sa nagpapaligaya sa akin ay ang pagsusulat. Hindi man ako isang propesyonal na manunulat ay para sa akin ay malaki ang halagat nito.
Isa lang akong ordinaryong mag-aaral na unti-unting nagkaka muwang sa aking kapaligiran at bansang aking kinalakihan.

Minsan ay aking napagtanto "Bakit ang ibang bansa tulad ng Amerika at China ay mas angat kaysa sa atin na kung tutuusin ay mas madami tayong natatagong yaman na siyang kinaiingitan ng iba.

Sabi nga ng iba Ay dapat noon pa ay mayaman na ang Pilipinas Dahil sa mga nakaupo sa puwesto na nasilaw sa pera ay naging ganid at "CORRUPT"

Ngayon ay kaydaming mamamayang Pilipino ang gumagawa ng illegal upang magkapera. Kaya kaydaming Pilipinong uhaw sa tubig,pera at pagmamahal.

Bakit ko sinasabi ito? Bakit ko kaylangan ilagay ito dito.. dahil gusto kong malamn ninyo na marunong din kaming pumuna at bukas ang aming mga mata! Habang akoy naglalakad sa labas ng simbahan ng OUR LADY OF GRACE PARISH ay kitang kita ko ang mga palaboy ng bata sa labas ang iba'y nakahiga sa mercury drugstore.. At sa ST> JOSEPH THE WORKER PARISH na malapit sa amin ay puro nag rurugby ang mga bata doon na ang iba'y buntis pa. wala naman kaming magagawa at baka magalit pa akin kung pigilan ko sila kay buti n lng nahuli sila at ipinadala sa DSWD at nsa mabuting kalagayan na sila. At sanay mawala ang mga taong nag rurugby sana din ay huwag na ninyong bigyan ng pera sila kundi tinapay o kahit huwag na lng.

"KAYLAN KAYA MAGKAKAROON NG ISANG MABUTING LEADER ANG BANSANG PILIPINAS?? "

Holy Week

Holy Week is a time where we commemorate the death and resurrection of Jesus Christ.
In a way that we do some old practices just like Visita Iglesia , Doing 14 station of the cross, Not eating meats , Watching Senakulo and many more . when days past by many changes happened., since many people now are busy just like my parents.. we dont have time to do this things. But since we are Catholic and it is part in our traditon we need to follow what have our family does.

14 station of the cross

-->Before we do the 14 station of the Cross. We watch the priest and take a picture on it.

then on the next day we went To Quiapo

--> There are so many people. But we didn't give up even though it is so hot. And thanks God we survive that thick people and we went home very tired and look like we didnt take a bath even in just 2 dayds? :D
