wow so many upvotes, I really appreciate it. I recently deleted my account, I had many penpals, so I sent each one of them a goodbye letter. in that night i somehow dreamed of a goodbye stamp, that's how i came up with it.

it was a stamp that included blue, and white that includes a short goodbye letter, forever.

AI made this stamp, just to visualise it.

Saying goodbye can be done in a number of ways. We'll need a series of these stamps.
