I erred. Most people make errors, some are too insecure to admit so.
I do all the time. I even apologize for them.
That never occurred to you, though, did it?
So...you fucked up, and it's MY fault.
You really are not very bright, are you?
Then why do you pretend your opinion matters?
I have owned three homes and can read and follow directions. So my skill level in home repair is about that of an E-6, competent but not skilled enough to supervise others. Career wise I supervised managers who supervised supervisors.
And once again, you speak of matter of which you know nothing.
E-6s are supervisors. As an E-4, I worked unsupervised because I knew what I was doing. As an E-5, I led maintenance crews and wrote performance reports and decorations. As an E-6, I managed a billion dollars' worth of equipment. I told (respectfully) O-6s that they couldn't have the equipment they wanted. When I retired, my Director, another O-6, said he'd heard nothing but compliments for my work from those same O-6s whose requests I turned down. Generals and command chief master sergeants have given me coins for my work.
Now, do you really want to continue bloviating about construction and the military as if you know something about it? I really don't mind making you look stupid.
Or, if you'd rather, before you post, you could ask yourself, "Have I ever done this?" If the answer is no, then you could just STFU and not look like such an arrogant prick.
But that never occurred to you, either.
