It doesn't really bother me when they don't "get it." I'm lucky in that my mom and sister think they are cool...but my brother and his wife are more like, "Seriously? Eww!" ...... And my husband just tolerates them. He doesn't "get it" either...but he loves me anyhow.
And that's the key. I love my friends and family for who they are...not because they agree with or enjoy everything I do. I won't change my passion for snakes just because they don't get it...and on the same point, I don't expect them to suddenly "get it" and change their way of thinking just because I want them to.
If someone is open to hearing why I like them so much, I'm very happy to explain. But I don't force it on anyhow. If someone gets a bit uppity or snooty about my having snakes...I just shrug it off and think to myself how sad it is that they lose out on so much by being so closed minded.
