I have a coworker who talks the most during scrum and not saying anything of substance or actionable in that whole time. He answers questions with a sentence paraphrasing the questions putting himself in a third person, waived him of responsibilities, but acknowledging the issue in the asked questions without providing any real solutions, leaving us looking at each other wondering wtf just said. But all knows too well not to ask a follow up questions. Or you gonna be here a while.

Utter waste of my time.
