In olden days we used to write with pen and paper only. No computer.
While writing a letter, say, I might have made a mistake. And there were no erasers for pen writing. Only way was to strike off with pen the unwanted word or sentence.
Suppose I had written a sentence " I don't know". Then I realized that this sentence "I don't know" is unwanted. I needed to strike off this sentence "I don't know" with one line or more lines on these three words.
What I would do is super-write "I don't know" with "We can fuck" or some other small sentence. Then strike the sentences with lines. This would ensure that a curious reader is not in a position to make a guess as to what was striked off. Because neither "I don't know" or "We can fuck" will be readable. Because they are now written one over the other and striked off too.
Well, well. Gone are the olden days !!
