Something odd has happened. The following ancient thread “My Conversation time…” appeared in the Recently Active Threads, without having been added to. (Well, now I’ve added something to it.)
@SanneT - yes, a bit strange 
seems like some ghosts are playing here Since the thread is “recently active” now due to your new comment, it is hard to find out why it was activated before. If you notice such a strange thing again, please let us know! Sorry about this confusion.
