Belajar majas itu asyik sih. Cuman radq sulit karena jarang baca puisi
Maam, I have a doubt regarding Daltonism. Daltonism is related to color blindness especially the insensitivity to red light, right? You said it's night blindness which is a different topic.
I'm sorry I spelled it wrong.. it is related to color blindness
