How did Aunt Baba feel after Adeline got her first medal?

From the text:

My aunt looked thrilled. “So soon? You only started kindergarten a week ago. What is it for?”

I watched her open her closet door and take out her safe-deposit box. She took the key from a gold chain around her neck and placed my certificate underneath her jade bracelet, pearl necklace and diamond watch, as if my award were also some precious jewel impossible to replace.
