When I first started in reptiles I was a horrible keeper. I thought as long as the snake was warm it was fine. Well I put them almost to the roasting point. I would use those huge floodlights with nothing being controlled. But some people relize there not doing it right and change and some people just dont care. Im going to say your friend just didnt care especially after you told him what needed to be changed. I have old pics of when I first got into snakes and had aquariums EVERYWHERE.! And it makes me sick to even look at them. But I keep them around to remind me my animals come first if there not healthy and kicking I need to find a new hobby. Good work trying to help the snake but some people just dont care
