#3 "New Pretty Town" p. 3

"She waited peering down the hall anxiously, panting into the hot plastic of her mask. "Ground floor!" she repeated. "Close door!"

Nothing happened.

She sighed, closing her eyes. Without an interface ring, she was nobody. The elevator wouldn't listen."

I chose this as an example of irony because Tally took off her interface ring so she could be free to go see Peris, but then when the pretty boys were chasing her, the elvator didn't see her so she was trapped.

Tally chose to wear a mask to the "white tie" party because she didn't want the pretties to know she was ugly.

This site talks about masks being part of desguises of costumes that are worn over the face and that they are good for hiding any emotions or features on the wearers face. This relates to Tally's descision because the mask hides her ugly features.
