Louie's mother was actually a housewife. Childish and foolish, Louie thought that she was a bottle-washer, often noticing her washing bottles. Despite that, he wrote that she was a nurse, to keep up appearances.
I have two questions actually:
Childish and foolish, Louie thought that she was a bottle-washer [...]
Is it correct to place adjectives before the noun like that?
[...] he wrote that she was a nurse, to keep up appearances.
Is the use of keep up appearances
correct in this context?
