My nemesis is a guy I work with who I will call John. John is actually a pretty sucky nemesis because I don't know him very well. John is about my age, I think, and that's pretty much all I know. He started at my office about a year after I started, but we were never introduced. We are both in the same general group and have the same job title, but we have different bosses and are on different floors. So anyway, one day, not long after John first started, I saw him in the hallway and said hi. He totally ignored me. It was kind of weird, but not really a big deal.
A few weeks later, I went to lunch with a group of about 12 people. John was one of the 12. We were standing around, waiting for the last few stragglers, and I happened to be next to John. We were facing each other. I said, "Hi, John. I don't think we have ever officially been introduced. I'm -R-." John looked right at me, turned around, and started talking to the person behind him.
That was the last (and really only the second) straw. John became my nemesis. I have seen John many times since he became my nemesis, and he has never once acknowledged me. It is pretty hilarious.
My friend at work and I always report to each other each time we run into my nemesis. John actually talks to my friend, so my friend lords it over me, as though being acknowledged by John is some great accomplishment.
Today, John sent an e-mail to everyone in our group asking if anyone had this work-related book he needed. I had a book in my office on the same subject, though it wasn't the book for which John was searching. I wrote an e-mail to my friend that said, "I have a book on the same subject that my nemesis is researching. But I'm not going to tell him. Take that!"
And then I sent the e-mail to my boss instead of my friend. Then I crawled under my desk, curled up in a little ball, and died.
Actually, then I called my friend and told him what I had done, and we laughed for a really long time because apparently we both enjoy my total humiliation. My boss later replied to my e-mail with, "Did you mean to send this to me?" I wrote back, "What?" So I guess my strategy is to pretend I am hard-of-hearing via e-mail. I do not know how this strategy could fail.
