You may ask your manager for a favor one more time, no harm in doing that. But that is not the real solution. You best buddy might change his job one day. You cannot ask the hiring manager of his new company to offer you a job there, can you? So, always brace for changes in life. Change is always good. The fear of the unknown has prevented many a bright souls from realizing their true feat. Always step into the unknown and stumble on pleasant surprises that life has to offer.
