Get the your mummug. A very strong character who does not stand for any nonsense. If you’re on your phone for any more than 5 minutes a day, then you may as well say bye to it for the rest of your life. Although she may seem mean, she is a lovely woman; however, her youngest daughter tests her patience. To everyone else, she is a pleasure to know and very pretty. She also tends to like tall, brown haired boys who get 29 commendations, but then again, who doesn’t?
