When you are forbidden to do something and you think the it’s not reasonable, it must be quite natural to have a desire to break the rules. The first time I learned the word ‘peek’ was – as you know English is not my mother tongue – indeed such a situation. No! I wasn’t peeking in someone’s private life. I was digging inside a micro computer using a high level programming language called Pascal. The operator PEEK meant retrieving data stored in a memory. It sounded so strange for me because its antonym was POKE which operated as writing data.
Back to my picture at the top. The round window is for seeing outside of the tight cabin. Nobody peeks in, probably.
