Behavior sounds a bit immature.

In fact, I have taken a couple nice deer. My brother who has not got a buck yet, likes to hunt with me... Why. Because he knows I give up my best spot to him each and every time we go hunting. In fact, I like to put him on deer and hot spots just so he has a better chance. He missed a nice buck and took his first does on the best spot I ever had. That same day, he could not shoot at a big six I was after all season. I could have from the same stand.....did not bother me a bit.

IMO - You need a real hunting buddy who wants you to get a deer and shares in the joy of the hunt.
