I agree stealing it is not a good idea, but I don't think talking to the guy would do much good. People who don't care enough to learn how to take care of pets on their own tend to dislike unsolicited advice. Unfortunately, they never go, "Oh boy! You mean I can actually put some work and money into this thing instead of continuing to do nothing?! Hot dog!"
However, because I agree that you SHOULD be able to communicate with people, you have to at least try. That might be enough to get him to come off the snake.... worked on my bro-in-law.
