Begin rant... in my opinion I think it's really rude to pull someone away to talk to them in private when you're sitting right next to them. My SO's mom does this all of the time. She'll pull him away and than close the door and talk to him in private and I'm sitting here like really? You could be less rude and ask to talk to him when he gets a minute or wait until later. Like she literally just walked through the door and didn't say anything to me and than pulls him aside. Makes me wonder who she's talking about. 😠😠😠😠😠
