A Mark

A mark is a paint given from our past,
That brings back the color of yesterday;
It comes by intent or a sudden cast,
Through things that hold sentiment to replay.
And serves as a bridge between two islands,
From the former till to the current state;
With a trip that doesn't need any funds,
As long as you've written it on the slate.
But the marker will dictate the fixed mark,
As with what the bearer gave to its heir;
If it is sorted as gloomy and dark,
One will be embraced by sinister air.
However it still plays its role and part,
To teach by example straight to our heart!
