I think you will eventually meet many people in life. You may have mixed with them and were very happy, but one day they will become distant and forgotten due to time distance. But as long as you remember, you have been happy and happy.
I would like to dedicate this to my friends who I haven't contacted for a long time and have nothing in common. My memory is like an hourglass that decreases a little every day until I forget you.
But I wish you happiness forever, in the same world but in different circles. May your memory be like an hourglass, leaking to the bottom.
