You are evil, and I want you to be my friend.
I agree. But just remind me to never, ever, under any circumstance piss you off.
I can be evil but this wasn’t an example of that. I didn’t switch his password or anything. But I had been given the password by his predecessor who also had me do work on his computer (but was smart enough to at least learn how to do things for himself in case he ever needed to). When my old boss retired the new guy came in*. He expected us all to be impressed by how amazing he was (I never bothered to tell him that they had offered me the job before they gave it to him - in fact, I had been offered it back before they gave it to his predecessor).
So I kept on doing the things I had done for my old boss. And when my new boss saw this, he immediately began dumping more work on me. But quite frankly the work was pretty simple and I had time on my hands so I went ahead and did it. This continued for several years and then I left because of an argument with the boss’s boss.
Now is it my fault that in the several years in which I had been doing all that work, my boss never asked me to explain what I was doing? Or ask how it was done? Or even ask what the password was? I never bothered volunteering to teach him because he never paid attention to anything that he didn’t initiate on his own. But you’d think at the very least that when he realized I would be leaving in a couple of weeks, he’d finally figure out he was going to need to know this stuff. But he apparently was oblivious to what I had been doing for him all that time. I guess he still expected that all that work was somehow going to magically keep appearing on his desk even after I left.
*Not completely true. There was a year between old boss and new boss when we had dumb boss.
