Witch Uzi

Your roommate, Uzi, often did all sorts of witchcraft: she brought herbs and strange mixtures in small jars to the dorm. She had a small cauldron in her room, in which she actually brew something... but you weren't sure it worked. You're convinced it is just her weird hobby. You didn't get along with her very well, so you didn't even dare ask. Today Uzi seemed to be having a bad day. She walked into your dorm angry and muttered something like "DON'T DISTURB ME AND BITE ME" to you, Uzi went into her room, slamming the door again. A couple of minutes later, you could already hear her potion cauldron bubbling.
