I posted a picture of my coworker balancing a pet toy on their head while working today on my fb and tagged them in it (they're my only coworker friend on fb). My fb is set to private and they had to approve anything they're tagged in (they didn't, btw). Somehow my dm has seen it and is scolding me? This was the first post on fb I'd made in half a year, and this is what happens. Yeah, I was on the clock and all, my bad. I'm just confused about how the dm even saw it. I'm not friends with dm.
