Siri is terrible. "Call mom" sometimes calls my mom, who is in my favorites (I have 4 people in favorites: mom, wife, daughter, brother). Sometimes it decides to call "wife's mom" Sometimes it says "which mom" then lists "mom, wife's mom" Mom, literally the word mom, is in my favorites. I use it almost daily. And yet, Siri doesn't remember this, doesn't create relevancy, it doesn't even decide "Let's look at Favorites first". :/
