but at this party i guess i made the mistake of calling him my ' best work friend ' . he was offended . little did i know ... that was just the beginning.it was only until about march , my birthday month , where we did nearly everything together . he quit his job and went off to his first career and a digital imaging artist .
According to the above context, answer the following question.
What may be the reason that he was upset ?


He wanted to be more than just a friend from work .
