Now we part ways, each to our own course.
In youth, our ambitions were bold and strong,
But now in old age, thoughts of each other linger long.
Memories fade like dissipating smoke,
New worries rise like surging waves.
Wish you could gather more of these feelings,
For they are what most deeply move us.
