I Sit and Think by JRR Tolkien

I sit beside the fire and think
of all that I have seen,
of meadow-flowers and butterflies
in summers that have been;

Of yellow leaves and gossamer
in autumns that there were,
with morning mist and silver sun
and wind upon my hair.

I sit beside the fire and think
of how the world will be
when winter comes without a spring
that I shall never see.

For still there are so many things
that I have never seen:
in every wood in every spring
there is a different green.

I sit beside the fire and think
of people long ago,
and people who will see a world
that I shall never know.

But all the while I sit and think
of times there were before,
I listen for returning feet
and voices at the door.

---JRR Tolkien(1892-1973)

This is my favourite poem of all times.
In this limited lifespan we have on Earth, many sights remained unseen, breaths untaken, thanks not said, forgiveness not given, love not spread.

If we had unlimited time on this world,what joys would there be if there were no sorrows from partings?

Eventually, there would be no difference between Mondays and Saturdays, New Year and Friday the 13th.

Who knows? We may all become lifeless zombies.

What begins must come to an end.
This is the magic of life.
