...
Music in my ears
Slowly getting back to work
Focus on my task
Reading, creating
It will be used by many
Functionality
Code is the language
Tell the machine how to make
What I want to have
Mistakes do happen
Bugs and errors sneaking in
I'm tracking them down
Tests and checks help me
Find the places I have missed
To fix my mistakes
Everything goes smooth
The program behaves at last
A smile on my face
Time for the next task
There is always more to do
And more things to fix
