What does blind postscript mean?

Answer 1

A blind postscript (P.S.) is a message added to a letter or document without the recipient's prior knowledge. It typically appears after the main content and can include additional thoughts, reminders, or information that the sender wants to convey. This technique can create a sense of urgency or intimacy, as it often feels like a spontaneous afterthought. In some contexts, it can also refer to a message meant for someone else or to add a layer of secrecy.
