I sent a message to someone, then I decided to add few more comments in my second message to him.
So I opened the Sent items, and clicked on the P.M. Once opened, I typed in the fast reply textbox, and surprisingly the reply was sent to myself.

Is this a bug, or a feature?

EDIT: Please note that I haven't received any reply from him, so I couldn't click any P.M. in Inbox.

thats normal if done via sent items.
there is always a pm button further down each users avatar in the thread, or in their user profile.
