I once got a great job. My new director sent out a company wide email announcing my hiring. To make a former girlfriend jealous I forwarded it to her.
She responded, “Congratulations. I am glad for you.”
Not satisfied I began to rehash why we broke up and how she was instrumental in my receiving the job but now she would not reap the benefits.
She responded with a curt reply detailing my flaws and the events that led to our breakup. I sent an email back detailing how rotten she had been to me as well. The chain continued for about seven emails back and forth until she finally stopped replying.
The next day my new director called and informed me the offer was retracted. Apparently everyone in the organization had been cc’d the entire exchange between us.
