That’s what you get when you build a round tower
with bricks that are made of sand and clay.
It has to withstand wind, frost and shower
year in year out and day by day.
Ambitious projects such as these
often defy their special strains.
The raindrops in the rips can freeze,
walls break and invite further rains.
Thus when planning a construction
materials should be wisely sorted.
If not at hand a smart deduction
be that the project is aborted.
