(April 2015) (Learn how and when to remove this template message) Part 1 Alice in Wonderland[edit] The first part opens with Alice helping Mother set the table for tea time. Although thankful for her daughter's help, Mother tells Alice that she is still not grown-up enough to join the adults at tea. Alice goes outside to see her sister (played by Natalie's real-life older sister Sharee Gregory), but gets bored of reading a book with no pictures. Her sister tells her that she will understand when she grows up, but Alice thinks she is already grown up (after all, she's seven and a half). While playing with her kitten, Dinah, the White Rabbit comes running by, saying he's late. Wondering where he is going, Alice follows him and tumbles into his rabbit hole. (Unlike the book and most movie versions, this rabbit hole appears to be dark and spooky.) Alice finds herself in a hall with many doors, and all of them locked. On a table is a key which she can use to open one small door. Yet the door is far too small to even fit her head in. A small bottle appears labeled "Drink Me". She comes back to the table and puts it to her lips. Doing this, she shrinks to the right size for the door, but can no longer reach the key to open it. She then sees a small box which she opens and finds a little cake with the words "Eat Me" on it. She then grows to over nine feet tall. Frustrated with the thought of being stuck at nine feet tall, she begins to cry. Her tears fall on the floor and flow under the cracks. The White Rabbit appears, but frightened of the giant Alice runs away dropping his fan and gloves. Using the fan makes Alice shrink again to a size small enough to crawl into one of the cracks, which takes her diving in her pool of tears. While swimming in the pool of her own tears, she meets The Lory Bird, The Dodo Bird and the Mouse, who tells her why he hates dogs and cats ("I Hate Dogs and Cats"). Alice catches up with the White Rabbit. He mistakes Alice for his housemaid Mary Ann and orders her to go get his fan and gloves from his house. While searching his house, Alice curiously finds another "Drink Me" bottle and it makes her sprout to her full nine-foot character once again. Angry at Alice, the rabbit and his friend Pat the Pig try to employ Bill the Lizard to remove Alice by pulling her out the chimney. Having tried unsuccessfully the White Rabbit and Pat begin throwing berries at her which turn into little cakes. She eats one and shrinks to back to size. After running away she meets the Caterpillar who tells her the story ("You are Old, Father William"). She then goes to the house of The Duchess and her pepper loving, plate throwing cook. Finding the house too violent and hateful, she takes the Duchess' baby away, but then it turns into a pig. She meets the Cheshire Cat, who tells her that she can't get out of this land ("There's No Way Home"). He then gives her directions to see either the March Hare or the Mad Hatter, but warns Alice that they, along with everyone else, are mad. Alice finds the Mad Hatter, March Hare, and the Dormouse having an outdoor tea party, and sits down to join them. As tea time entertainment the Mad Hatter, who does not like her version of twinkle, twinkle little star, sings Alice a song of his own ("Laugh"). Upset by the rudeness of the Mad Tea Party, Alice runs off back on her quest for the White Rabbit, and meets a baby fawn in the forest, the only normal thing she's seen so

[Q]: Context: My grandmother often said to me, "You can count the number of your true friends on the fingers of one hand." For a long time I thought this was true. However, I've now discovered my grandmother was only half right. Maybe we do only make a few "best" friends in our lifetime, but those aren't the only people that we can call friends. There are many different types. Let me tell you about a few of them. One type of friends is the type I call the "football mom friend". My neighbor Sally is a good example. We both have kids who play football in a football club, and someone has to take them to practice and pick them up. Sally and I and two other mothers take turns to do this. We meet sometimes and have tea and talk about what our kids are doing, but those are the only times that we meet each other. I enjoy being with these women, but we don't do anything else together. Another type is called the "hobby friend". That's the person you share an interest or a hobby with. Michael and Cater, who are brothers, are a good example of this type. We're all in a bird watching club. Every few weekends the members of the club go on a trip to watch different kinds of birds. There's nothing romantic about my relationship with Michael and Cater, of course. We just share interest in birds. Then there's the "other half of the couple" type of friends. Jim is married to Rose, a friend that I've known since college. When Rose married Jim, I realized that I would have to be Jim's friend if I want to continue to be Rose's. Jim and I don't share so many interests, but we do have a friendly relationship.
