Picture this. You need to buy a new toaster. Only you live in a parallel universe, where toasters are only available at very specific stores, and you’re a person who can only eat toast. For whatever reason, nothing else will work for you, only toast.
Now you know you can’t get toasters at any store. You go to your local shopping mall. Only you walk all over the place, and you just don’t see any toasters for sale anywhere. Finally you ask for advice from the info desk, and they look at you a little disapprovingly and say “Umm, I think there’s one toaster shop over on the far side of the mall.”
