Dan kemungkinan yg lain, who knows they’re probably extreme introvert? Bila kena approach rasa anxious. Or a reserved person. Atau tak biasa dibesarkan dgn having small talk. Ada yg I kenal beberapa orang ni, diorang sejenis battery dia mudah drained. So kadang dia betul2 reserve energy dia utk perkara yg penting2 shj. Contohnya, content yg dia dah dibayar. Kita bayangkan shj lah mcm stage performers. Diorg pun banyak diam & tak bercakap dgn orang ya before nak perform. So something like that.
