Rude:

It all happened so suddenly - the comment, Nagisa leaping up and throwing his drink in the waitress's face, and then being kicked out of the restaurant - that Makoto didn't really know what to feel.

"Mako-chan?"

Nagisa was peering at him anxiously, braced for anger.

"She was really rude," Makoto allowed.

There was a moment of silence. Then they were leaning against one another for support as they laughed like idiots.

"You realize that they'll never let us back in there?" said Makoto, wiping tears from his eyes.

Nagisa just grabbed Makoto's hand.

"Who cares? Let's go get ice cream."
