Have 你 ever been so scared for someone, 你 actually shout something like NO! 或者 something?
I hope I'm not the only one. Well, I only did that once, and it was when my sister got hit 由 a huge bus. She was taking me to school when I was like 7 and she was 15, and the sign didn't say go yet, but she wasn't paying attention, and she just crossed the road while texting, and a bus was coming, so I said, "ONII-CHAN!" ( sister in Japanese) and the bus hit her and she died.
