Some things last forever

Some things last a long time

Some things last a lifetime

And something last for...never

The oceans will stay filled with water

Mountains will last for ages

Trees will live for quite a while

And compared to these, we last never

Yet you and I will last forever

Or memories will not be forgotten

Physical presence lasts but a lifetime

And nothing last never

Foot prints in sand go away quickly

In mud, they last longer

In deep snow, they last hours

But on the moon they last for millennia

You have jumped upon the moon's barren surface

And those footprints will last

They will be a reminder

Should you ever return
