Sense of smell

She came into our unit
Friendly visit on her mind
We simply didn't realise
She wasn't being unkind...
"Can't you sense that smell dear?
I know where it's coming from?
I had the very same problem
But now at last it is all gone!"
Water had been slowly leaking
Way before we had even realised
Black mould spores were brewing
We'd underestimated their disguise
Hidden behind kitchen cupboards
Those evil spores had multiplied
Spreading their spectacular destruction
We could not smell it, were sensitised
That awful smell; spreading far and wide
The previous tenant had voiced it
Her concerns; though never recognised
Nothing was ever done about it
No cleansing regime improvised...
Now as we were finally leaving
After the work was finally done
We'd left to move our belongings
Came back to check before moving on
The mouldy smell was overpowering
How could we not have known?
It pervaded all our senses
Made us finally realise...
That cough that ever lingered
That rash that never fully healed
Just as we had read all about it
These ailments were now revealed
As part and parcel of that moisture
As caused by that ignorance
For they surely would not listen
As she had tried to seek recourse...
Now at last we say "good riddance"
To that substandard rented home
I only hope the next tenant will
Get to enjoy a cleaner zone
