We can look at the eyes of the lady in the portrait how stoicism was expressed. The girl's eyes express loudly how tired and dead she is inside and it relates to the meaning behind the title. In my own understanding, "Huwag Mong Damdamin ang mga Bagay Dahil ang mga Bagay ay Walang Damdamin" tells us that we should not feel things as deeply as we should because at the end of the day, they are just "things" that happen. But I think this kind of thinking devoids our sense of feeling as deeply as we should over a situation that actually touched or pierced our heart. It dehumanizes us in a way to "not feel" things. The lady on the portrait looks "lifeless" when you look into her eyes, it's as if she has removed everything that is human in her— her ability to feel, to rage, to cry, to drama, or to feel an emotion on something.
