I am an Eldritch Abomination made of limbs, so I can be considered a Witch. If your enemies annoy you, I can curse them to hit their toes on every corner they pass by, cut their fingers every time they try to peel a potato and many more annoying or dangerous things. There is enough snaks, boxes and space in my house for a cat to explore. As for the life advice... I'm Russian, we live questionable lives full of strange life advices.
Example: if you get stopped by any gopnik, you should try to become their friend. If that fails, you can always say that you've been already robbed a couple of blocks "that-a-way" so their attention goes elsewhere.
