It is safe to say that if you ever receive word of being diagnosed with a terminal illness, chances are you will immediately think about all the milestones in life that you will miss. For one Dad from Billings, one of those milestones is seeing his son graduate High School.

John Raines is diagnosed with terminal brain cancer. Doctors told him that he has roughly six months to live. But, John's dying wish is to see his son Blake graduate. He says "What parent doesn't want to see it." Blake is a senior at Billings West High School. He is on course to graduate in June. But, John fears he will not be around that long.

So, in an act of kindness, John's ex-wife arranged for an early ceremony for Blake. Complete with gown and school band playing "pomp and circumstance."
