Be careful, Do you want to die?
Every day I cross a street intersection with too much traffic and I see people crossing it in a risky fashion. Because of this, sometimes I feel tempted to ask them: Do you wanna die? Of course, asking that would be too rude, but I have the question of how it should be asked, without any intention to do it.
你要不要死?
Nǐ yào bùyào sǐ?
