Interesting Quests and NPC in Diablo 3

Most Diablo 3 players are crazy about killing bosses and getting legendary gears and loots. I am a girl who isn't so addicted to the savagely battles with monsters. I am playing Diablo 3 because I love the interesting conception of the quests and NPC in Diablo 3. An interesting quest itself would become a bigger surprise for me than an awesome gear, not to mention NPC with special characters. It is really an interesting adventure for me.
I would like to share some of the interesting quests and NPC I encountered, they impressed me deeply. You may have ignored or forgotten the story or the courses. I am more than pleased to help you review these scenes.
Firstly, I would like to say something about "the lost goast in the well". Do you remember her? The lovely and poor girl's goast was lost in the hell in a well, she didn't want to ascend to heaven as she lost her doll bear. In this quest, you are asked to help her find her doll and drop the bear to the well.  I sympathize the girl so much after I knew her story, she has lost her parents and relatives, all she has is the little bear. How sad she would be! When I finally found the bear and gave it to her, the girl float up into the sky, I feel as if I saw a happy angel. The beatiful scene of her ascending made me feel so gratified and happy.
The little girl made me feel so sad, while another character made me feel so complicated. She is a mother named Alesar. I met her in the quest "Alesar's Pendant". In this quest, I was asked to help her find her necklace weared by her little son, but his son was eaten by an Sand Thresher. I remember her beacause she was so different. Other than feeling so sad for her loss of her son and eagered to conduct a revenge, she even felt glad. This weird woman made me feel pity and angry at the same time. I think she was just concealing her true feelings towards her son. Her son's death made her feel so sad, but she didn't want to face the truth, maybe it is easier for her to hate his son rather than kept missing about him for the rest of her life. Even though I know her true feelings, her kept of scolding his son still made me very angry. This weird mother made me feel so complicated when I was killing the Sand Thresher, I am afraid when I killed the monster, would there come out a body or the parts of the little poor boy?
In another quest "Collapsing Tomb", I was aked to run out of a tomb that full of treasures in 4 minites. In these four minites. The tomb was shaking and large rocks was falling from the ceiling. It was so dangerous, I had to avoid the rocks, fight with the monsters and pick up treasures at the same time. I want to get as much treasures as possible, but, like the ending of every movie, greed would only lead people to death and lose of everything. So I get out of the tomb at the right time. How  thrilling it was! I could still remember the feelings then.
These quest made me feel as if Diablo 3 is not a game, but a story book. I could always encounter different characters with different experience and I would always be willing to listen to them. The different with a story book is that, though my hard work, I can change the end of the story at last, which adds much more fun to this book. There is only one pity, that as I am not so good at farming gold and I do not have very strong weapons, it gets hardr and harder for me to finish quests in the latter levels. Maybe I need to buy some Diablo 3 Gold to exchange for some awesome weapons, so I can experience more stories. It is undoubtly that this game is gonna be more and more interesting.
