It is glass but it isn't wine?

Question

This riddle appeared in NYT Magazine in late November. Anyone got it?

"I say a word, and then I tell you if the word is or isn't it. For example," I picked up my wineglass, "it is glass, but it isn't wine."
"Now you can ask me one word, and I'll tell you if it is or it isn't, and we keep going until you figure out what the difference is."
"Is it a plate?" he asked.
"It isn't a plate, but it is a bottle."
"It's a rabbit, but it's not a box."
"It's a tree, but it isn't a leaf."
"It's Woody, but it isn't Mia."
"It isn't stop or go or wait, it's traffic."

So what is it?

"Life" sounds interesting, but then why is it glass but not wine?

Wine cup -- nice try :)

Doubt that it's about Christmas.
