HI! Maybe this route will work. Ask her if she trusts you(snake NOT present of course). Tell her how much you love her and how important it is to you that you and her come to a common ground on this. Ask her if she really thinks that you would ever put her in danger. Hopefully she thinks not. Tell her that you would not ever do anything that would ever endanger her. Let her know that it is something that you really enjoy and you would like her to understand how much the snake means to you. Let her know that you understand that she may never like snakes but how much it would mean to you if the two of you could come to some kind of middle ground. She must love you and is already willing to compromise some because she allows it to be in her house. My mom almost kicked me out of the house back in the day when she found out I was keeping scorpions without her knowing of them. Needless to say it was either the scorps or me moving to my dad's place. The scorps had to go. She is at least not kicking you or the snake out. That is a BIG start. Her interaction with the snake may never happen. But if you can help her to learn about them and at least get her to know that it poses no threat to her, she may be a little more tolerant. Remember, you may not ever get full acceptance. But, you may get some cooperation. Moms are amazing when it comes to the love of their children. If she knows how much you love your snake, then she will (hopefully) be more willing to work with you on this.

Good luck and Godspeed.
