If you have information… SHARE IT
I can’t stand it when somebody gives you something to do, but only gives you about 50% of the information needed to accomplish it. Then of course when you’re about half-way done you get “Oh, didn’t you do blah blah blah?”
Why do I have to recreate the steps you’ve already spent all afternoon on? ESPECIALLY if you’re going to tell me about it after I did it.
