Just today my boss decides to argue with me. He knows nothing, but like a lot of managers, he's The World's Smartest Man, and you aren't right unless he agrees with you.
Today's gem was about VoIP. We are looking at switching from RingCentral to another service. He is arguing with me that the new service should just work as long as I give them the MAC addresses of the phones. When I tell him that that isn't enough and that the phones need to know where to download their manifest from, he starts to argue. He knows nothing. He thinks you can route over the Internet based only on MAC address into a private LAN. I tried to explain that it's like giving your employee a unique employee number, and then trying to locate that employee anywhere in the world just based on the employee number. He didn't understand and continued to argue. Then, like he always does, he goes away for awhile to research how he is right and I am wrong. Inevitably, he finds out he was wrong and it's never mentioned again because important, arrogant, know-it-all assholes aren't allowed to admit mistakes. I feel like Quincy M.E. sometimes. Quincy is right 3000 times in a row, but the next case has everyone doubting him as usual (even though he's always right).
