That's a profile post you are seeing Peter, not a PM. When you click on an avatar or user name, you get a bunch of things. The first is profile posts.
mistook a profile post as a private message. If you just start typing instead of clicking start conversation, that's what would happen.
It all looks ok to me but prolly best not to use profile or status as a communication tool.
I will edit the post to remove personal info just in case.
