I open the word “container” and fill it with letters:
N, N, I, R, T, O, C, E and A.
Then I close the word.
The letters move around like beatles in a box.
Some are fighting.
Some are getting along just fine.
After a while, I notice a pattern-like behaviour.
The letters are forming groups of three:
C, O and N.
T, A and I.
N, E and R.
But I guess it was just my imagination.
