I think it may be a good thing to agree on what good manners are. I almost wish there was some sort of standard practice on this.<p>I know when I was starting out my career I had no idea what good manners were. One time at a milestone review I simply said: &quot;I had to rewrite X&#x27;s first pass he was using some older tech and there&#x27;s better ways of doing it now.&quot; and it really blew up. My boss took me in his office afterwards and told me that probably wasn&#x27;t the right thing to say that I had in fact insulted the other guy and he was hurt. Believe me it was never my intention to hurt anyone I was just stating what I did and what I knew. I apologized and we got along afterwards no harm in the long run.<p>That incident taught me to always be wary of corrections or talking about someone else&#x27;s work. They put their heart and soul into what they do and I should respect their code and them.
