Readers
so beautiful and so true.
the meaning
please tell me what do you mean by Yesterday is mystery
Where it is Today
While we shrewdly speculate
Flutter both away
please be so kind and explain it to me to understand what you mean
We can talk to the others
No matter how far away;
We can’t talk to the others
Even it was only yesterday.
i don't get it about why "YESTERDAY IS MYSTERY" while we passed it.
