English poems about time cannot be too long

It's sad when people you know become people you know.

How sad it is when those who were once familiar become no longer familiar.

When you can walk right past someone like they were never a big part of your life.

They were once an important part of your life, but now, you pass by them without saying hello;

How you used to be able to talk for hours and how now, you can barely even look at them.

You used to be able to talk for a long time, but now, you don't even look at them anymore;

It's sad how times change.

How time flies by sorrow.
