The passage of time is like water, and it will never come back. The scenery we have seen may be able to be seen again, but the people who have passed away will never look back. No matter how many thoughts you have, except for the occasional wandering in your dreams, the rest of the time he is just a vague impression. Many love affairs in the world are actually just lies told by time, but we are willing to persist in a lie without regrets, even recalling it for the rest of our lives.
