"I'm not interested in participating"
As a journalist and editor of ACR Latin America Magazine, I feel very indignant when I try to communicate with a certain company for an interview or consultation and their response is: "No thanks, I am not interested in participating."
Respecting, of course, all positions and decisions, I feel that these kinds of answers belong more to thoughts of the last century, when being conservative was a position that companies used to protect themselves from competition, so to speak.
