I have only been in a courtroom a few times post school and summer/semester clerking. The vast majority of times since then have been for jury selection when I was called for jury duty (counsel always excuses me). I have occasionally seen a lawyer tell a client to stop talking. Usually when they started talking directly to the judge or opposing counsel inappropriately and oversharing in a way that was detrimental to the case. (Telling your client to stop talking looks bad and signals poor client control, but sometimes it’s better to get them to just stop talking even so.)
I feel like sometimes in life, we all need someone to tell us to sit down and shut up because we are making things worse. That m/m author could use it right now. The new post at her blog (which I’ve now removed from my reader, thanks) is Not Helping. It’s all Poor Me! People are So Mean! While making it pretty clear there was an ulterior motive (sell more books!). Ugh.
