So if you reply after a post, it's a post-post reply, and if there's a button to post a post-post reply, it should read "Post post-post reply."

If there were a pole onto which post-post replies could be tacked, it would be a post-post reply post. If you were then to send this post to someone in the mail, it would be post-post reply post post, and would require post-post reply post post postage.

If one were to write something about that postage on FT, it would be a post-post reply post post postage post. And if one were to reply to that...

Enough already!
