The problem is, it seems to have rubbed off: I now feel inclined to indeed tell it like it is, but sometimes I have to stop and consider whether it is appropriate to give constructive criticism to people.
Today's example: a very craftily worded internal email. You have to read between the lines to figure out exactly what is being said. Would it be a bad move to reply to the General Manager of Customer Services, commenting that his announcement seems to be evasive and that he should adopt more straight-up language? I'm not in Customer Services, but something tells me my feedback may not be well received...
