• You're working on a certain client's work specifically for the day so your boss naturally thinks when you say "I was looking over their analytics" that "their" means the client that you are assigned to that day. Perhaps though your boss is also working on analytics for a different client and posted something in SharePoint regarding it and you were copied but didn't notice the notification email regarding the discussion, thus he/she thinks you are talking about the client he is currently doing work for.  It's a simple fix to just be more direct and say "I was looking over 'client name's analytics" so that you are both cohesively on the same page, you save time and frustration and thus are more productive and happier in your mindset.  What do you think?
