Do any of you have a friend that just can't hit the broad side of a barn with an arrow?

I have a dilemma AGAIN this year, as my friend is an older guy, @ 67 years old, that has hunted his whole life and is in rougher shape than most, with bad hips. In the past few years I have helped him set some stands, cleared shooting lanes for him and even placed him in my stands when he had nothing going on in his spots.

This year he is worse off than last and I feel I want to help him more, as he indeed is a good friend. We tend to hunt a bit differently, as I am a very methodical when it comes to scent and wind. Also paying attention to my entry/exit routes, so on and so fourth. I say this because I'm damned to put him in one of my good spots and have him mess up my area for the season.

Here's this mornings story...
I bring my 3 year old boy to his house so we can start practicing on the old targets. He shoots 9 arrows total - 3 arrows never touch the target and are lost, 2 hit the dirt in front of the target and the 4 that hit the target, well let's say 2 would have been "close" to the kill zone (6"). He proceeds to tell me he has target panic, but never when a deer is in front of him (ya sure).

He says he has been practicing all year long in his basement and doing great! He starts off by blaming his glasses, then he said it was a "single" flinch, then that he held too long before shooting. I was a bit furious with the whole ordeal, knowing I spent better part of a day last season looking for a wounded Doe. He tried to tell me it was a good hit maybe a little high, but no explanation when I find a batch of white hair (I asked him if it was an albino)??? Not to mention 4 years ago, he whacked a big buck and it had the same results.

Anyone have any suggestions on how to get my point across and not tick him off too much, as I do have respect for my elders?
