My friend came over, took a look, and asked curiously: Why doesn't my right eye shed tears?
Answer: I didn't say that my right eye doesn't shed tears.
Wipe a drop of sweat from your forehead and ask again: Is there a priority for tears? Did it flow out from the left eye first?
Answer: I haven't done any research and there is currently no definite answer.
So he became furious: I finally saw it, you are actually a liar!
In silence...
Ok
Since the left hand can be connected to the heart, why can't the left eye shed tears for the heart?
