Yup, we've all heard it. As long as people know we keep snakes, we'll get the negative, ignorant comments.
Brush it off, educate them if they're willing to listen and move on with your day.
Snakes definitely aren't for everybody (that's probably what attracts many of us to the hobby in the first place) and that's ok. It would be a boring world if we all liked the same stuff.
You do you. Do what makes YOU happy. Learn to ignore the ignorant and enjoy your pet.
