Not all plastic surgery is for the type of Goyische vanity your describe.
Not everyone who has plastic surgery announces it to friends or family.
The term plastic surgery is often assumed to mean ‘cosmetic’ surgery. In reality Cosmetic surgery is of the vanity type, while plastic surgery is of the restorative type: think burn victims, or someone who had had a disfiguring accident.
Some rhinoplasty is cosmetic, some is to repair issues such as a deviated septum.
I had plastic surgery 30 years ago on my hand after large bone spurs were removed. The excess skin was removed and a seamless reattachment was made. No visible scar.
My wife knew, my parents and siblings never did
