Hahahah!! That's the silliest thing I have ever heard!
I'll just tell you that Miko can taste the difference between red apple and green apple. He will not even touch red apple, not even a little piece and will turn his nose up at it, but goes wild over green apple. There are many other examples, but this is just the one that pops out at the moment. Oh my!!
The fact that her roommates dog eats paper is because dogs love to shred paper for some reason, not because they can't taste.
You're definitely not the crazy one.
