I am searching for a word which means someone who has an obsession with being 'Normal', or someone who cannot bear to be different from other people, or similar. Is there any such?
Context:-
A lives in a western country, and always eats rice with chopsticks. His mother B scolds him for not eating like a normal person. When he cries due to the rather vigorous scolding, he is again scolded for not crying properly.
A suitable adjective for B?
