Consider yourself one of us
As a child, my family saw the musical Oliver!. For days after, my adopting mother hummed and sang the theme tune:
Consider yourself one of us
Consider yourself at home
Consider yourself one of the family ….etc etc
The song is a bit of an earworm. I’d forgotten it and the memory until recently when I heard it on the radio.
If you’ve seen the film (or read Dickens), you’ll know that being ‘one of us in Oliver was conditional on acting the part. You had to abide by their code of thievery and obey Fagin, the orphan master.
It makes sense. Like Fagin’s gang, we humans are tribal.
