A lot of my coworkers had that kind of reaction when they found out I was getting my first snake last April. One of them was all 'just wait til it wraps around your neck!' and all I said was 'And what? Give me a massage, they're not strong enough to actually cut off the airflow in the first place.' 'Why not just get a dog?' "I live in a small apartment and don't have a space for the kinds of dogs I like... Not only that but that little snake will outlive any breed of dog and is more than happy just to flop and watch a movie with me."
The key to a lot of the negative comments is indifference with tidbits of true information. Usually when someone hears that most snakes will outlive their dogs they start asking more questions like what do they eat and how often do you feed them, how big they get, ect. One of my coworkers is actually considering letting her husband get a royal because he loves snakes after I was talking with her about mine and just how nice he was. Until he gets fed a half hour late, then he gives me attitude, lol.
