I asked the question on the 25th August,2016

You would use L7 for the coworker. I wouldn't get caught up on dispositors as a novice.

As a side note, I found it interesting re-reading my old post and realizing the Moon and L1 being the same shows a mind and body connection, and might be in part why astrologers associate lunar people as getting physically ill when they are emotionally taxed.

I need to try out astrojin's tip regarding the dispositor of the Moon for lost objects.
