Question: are there any friendly snakes?
Answer: Yes…. but let me qualify that statement. As with people, there are many types of snakes-with some that are 'tamer' than others. Keeping a snake as a pet-and handling it (needs to be the right temperament; e.g. Ball Python, Corn Snakes, Boas) - tends to make the snakes trustworthy, as they get used to human handling.
