Cats walking down a street on there own- connote loneliness, slyness- never really know what there thinking/ where they’re going.
A person (new school boy)- really quiet never spoke to anyone, people would find him weird and strange and never go up to him a speak either- he was quite mysterious.
He would just go to school, do his lessons, at lunch sit on his own writing in a book he never let anyone look in, and then at the end of the day disappear- nobody knew where he went or if he went home.
At the end it’s revealed that in the notebook he was always working stuff out for a painting he had been working on for a year (since his dad died).
He is a really talented young artist and then went on to winning loads of awards.
You never know what someone’s thinking or going through!
