London is curiously at ease
Invaded twice daily from overseas
But the Thames knows
Where it goes
Its tide with the moon communes
Mornings and afternoons
Changing its course
Each time flowing back to its source
Conjuring a tidal shock
Yet, before it gets to Teddington Lock
It does reverse thrust by necessity
To journey back to the Thames Estuary
But at a little less than walking speed
It’s clear that not all its waters will succeed.
So later on with tidal remorse
It heads once more back to its source
Washing the banks of London as it goes
Often with the same water as before
Little has changed since days of yore
The moon guides the saline from afar
Our riparian rock star
But as with Londoners there’s no disputing
The Thames just loves its daily commuting.
