"Once a teacher, always a teacher."

These are the words of a Physics teacher who went viral after discussing lessons despite hoarseness in voice.

She is Gwyneth Matibag, 60, from Muntinlupa National High School, who is now on her last term in teaching as she will retire in February.

Despite Teacher Gwyneth struggling to speak, she continued explaining to students her dedication and passion for teaching them.

"Pag ikaw ay teacher true to your heart, kahit may sakit ka ay iniisip mo [ay 'yung] estudyante mo. Ganu'n ang ina," she said in the video.

In an exclusive interview with DZRH News Online, the uploader Ronnel Mensenedez, one of her Grade 11 General Academic Strand (GAS) students, shared the story behind the video.

"Pagpasok niya po sa room, nagkwento pa po siya [na] ganito (paos) daw po yung boses niya ngayon. Tapos 'wag na lang daw po siyang sasabayan at 'wag na lang daw po siyang aasarin," he said.

"Habang nagtuturo po siya, nauubusan na po talaga siya ng boses. Tapos po inom siya nang inom ng tubig. Tapos pangalawang inom niya po 'yon nagtake na po ako ng video. Tapos sumakto po ro'n sa sinabi niya," he added.

Mensenedez was pertaining to his teacher's line saying, "Pasensya na, once a teacher, always a teacher."

He describes Teacher Gwyneth as a good educator and one of his favorite teachers.

"Magaling po siyang teacher na 'yung tipong kahit ikaw 'yung tipo ng estudyanteng mahina sa klase, magegets mo po kapag siya 'yung nag-explain," he shared.

His reason for uploading the video was to share to everyone how much they respect the educator — giving it as a present before she retires.

"Gusto ko lang pong ipakita na saludo po ako kay ma'am. Sana po hindi niya makalimutan kasi ito po 'yung pinakamasayang pagreretire na matatanggap niya. Kasi po na-appreciate siya ng milyung-milyong tao,” he explained.
