PM: This feature should take you about 6 hours to complete.
Me: Psh if that, it's just a view.
PM: Actually it needs this logic as well. *sends requirements*
Me: OK that's way more than a view... *gets it done and commits*
QA: I need this logic to work a way that was never on the requirements.
Me: Yeah, that's an additional feature but I'll do it. *commits and passes QA*
PM: So why didn't you finish everything on this sprint... you said that 6 hours was more than enough time.
