Ummm....well....what do ya think would happen if you were honest with her? Personally, I think it's wrong to be so disrespectful of a person you're living with as to bring animals into their home unasked...and doubly so if it's an animal they would have an emotional reaction to.
Try by showing her some pictures of ball pythons, maybe? And talk up the positive aspects of having a snake for a pet....such as: No barking, no shedding (not in the traditional mammal sense, anyhow! LOL), no clawing/chewing the furniture, no poop filling up the yard or staining the carpet....things like that.![]()
