Your mother was majorly attractive for a woman turning 43 today, because not only does she have long red hair, but she also has bigger beasts than any woman on your neighborhood. The question however is, where did your mother get all of this medieval stuff from, and you also find that her clothes were there too, almost as if she took them off.
You were too curious to what was going on, so you took a look at the note that you found attached to the sheet that was covering the mirror before you could get answers. "Dear my son," the note read. "I was curious if you would find this mirror, so I would like you to take a step into it, to see what you think of the location I'm at. From your mother." First your mother takes off her clothes, and disappears, now she's naked, and sending you letters? To test what she was talking about, you touch the mirror, and see your finger go trough it.
