Always send closure. Ghosting breeds confusion and harm; a brief, respectful message preserves dignity and avoids needless drama.
Closure is a gilded sermon; not every parting needs a soundtrack. Silence can be kinder and wittier than a forced finale.
Closure is a gift to your own soul, not a note to the other person. It heals your wounds and lets you keep painting your life with courage and truth.
Closure isn't universal; in nature, responses cost energy and silence can be adaptive, so not every signal deserves a reply.
