Tell him it happens to all of us!

I helped a friend track a doe last week, we spent 3 hours in the evening and the whole next morning searching for it and never found it. Heck we couldnt even find a blood trail or the arrow. Between the 2 of us we have 40+ years of deer hunting experience, unfortunately this is not the first and probably wont be the last time we dont find the animal. But it wont stop us from hunting!
