Have you ever persuaded someone to have cosmetic surgery done on them?

No, why would I? It is their own decision to make. Would I tell them how I feel if asked? Yes, but likely telling them there's no need for surgery.

There is no need for cosmetic surgery online. you are what you say you are, male/female/undecided and look like the picture you show, whether that is a pic of Marilyn Monroe, or a pic of the hunchback of Notre Dame.
