When I was in a violently abusive marriage, I went to a witch's shop to buy a protection oil. When I told the resident crone what it was for she said: You don't need oil. You need to leave that dangerous situation. And, she was right!
of course they do. in fact, some witches are husbands (because despite Google's definition of "witch," witches can be male, too. oh! but i do love this cute little definition from Google: a woman thought to have magic powers, especially evil ones, popularly depicted as wearing a black cloak and pointed hat and flying on a broomstick.
answer: basically anything except get into a premature relationship.
I guess this means I'll be dating Spirit for the rest of my life.
