What are three characteristics of Buddy's best friend/cousin in "The Christmas Memory"?

Buddy's cousin/friend is eccentric, imaginative, and very loving toward Buddy.

Buddy's "sixty-something" cousin is described as "still as a child." She becomes excited as she realizes that it is once again time for her to make fruitcakes. Calling to Buddy to fetch her hat, she and Buddy pull out a dilapidated wicker baby carriage that they take to a pecan grove, where they gather the nuts. She unearths her money, hidden in an "ancient bead purse" that is stored under a loose board under her bed.
That she is odd compared to others is exhibited by Buddy's listing of the things she has never done:

1. She has never seen a movie


2. She has never had a meal in a restaurant


3. She has never ridden more than a few miles from home


4. She has never sent or received a telegram


5. She has never read a book besides the Bible, or anything else other than the funny papers


6. She has never put on make-up


7. She has never uttered any curse words, or said anything hateful to another person


8. She has never consciously lied


9. She has never allowed a dog to go hungry

On the other hand, she has done some rare things such as taming hummingbirds to balance on her finger, known the recipe for strange Indian cures, such as a wart-remover; she takes walks in the rain.

• Imaginative

Buddy's cousin puts moonshine whisky in her fruitcakes that she obtains from Mr. HaHa Jones. The fruitcakes are made for "friends," who are really strangers. Buddy wonders if she imagines them as friends because they have not hurt her feelings:

Is it because my friend is shy with everyone except strangers that these strangers, and merest acquaintances, seem to us our truest friends?

When Buddy and she make a trek to find a tree, his cousin says,

"We're almost there; can you smell it, Buddy?" ...as though we were approaching an ocean.

After they return home, she opens a trunk with all sorts of oddities: ermine tails and tinsel. She and Buddy then sketch cats, fish, apples, watermelons, angels, etc. The cousin says she wants the tree to blaze "like a Baptist window." Later, as they lie on their backs holding to their soaring kites, Buddy's cousin alludes again to the Baptist window when she talks of dying, saying that when the Lord comes for her, it may seem like this window with colored glass and light shining through it.

The cousin calls Truman "Buddy" in memory of a childhood friend. She always writes to Buddy, and encloses a dime, telling him to "see a picture show and write me the story." 
When Buddy learns of her death, he describes the message in emotive language that expresses the love they have had for each other:  

...a piece of news some secret vein had already received, severing from me an irreplaceable part of myself, letting it loose like a kite on a broken string....I kept searching the sky. As if I expected to see, rather like hearts, a lost pair of kites hurrying toward heaven.
