Gum
"Oh man!" Toph said as she smelt her breath. "They put garlic in my soup." She complained. The school cafeteria was notorious for using cheap food. Toph thought that the cooks just mixed random ingredients together until they got something that didn't kill the rats.
"So what?" Aang said. He had brought his lunch with him and didn't need to worry about the school's food. Salad. Plain salad.
"So, my breath is going to be funky all day now." She threw her spoon onto her tray in frustration. "Come on." She said as she got up. "I gotta get something from the vending machine."
"You're gonna eat junk food for lunch?"
"It wouldn't be the first time. You coming?"
Aang sighed. "Fine." They left the cafeteria and entered the empty hallway.
When they were alone and out of sight, Toph reached into her back pocket, pulled out a stick of spearmint gum and began chewing. She passed the vending machine without stopping. Aang knew what she was doing.
"Does my breath smell okay now?" She asked and moved very close to Aang, blowing on his mouth gently.
"Much better." Aang said, calmly.
Then Aang kissed her. Toph loved it when he made the first move; he felt her lips smile. Toph pushed him, quietly, against the lockers and began kissing him back. The two lock lips for a few nonstop minutes of innocent and dirty teenaged bliss.
"Aang!" Katara's voice echoed down the hallway.
"Oh crap." Toph pushed him off of her and Aang straightened up.
"Aang!" Katara kept yelling.
"Um, yeah?" Aang hollered back at her.
"Moron. What are you doing?" Toph asked.
"Aang." Katara ran over to him and smiled. "Hey."
"What are you doing here?" Aang asked.
"Yeah, don't they keep you busy at college?" Toph as a little grumpy.
"Yeah, nice to see you too Toph. I have off on Thursday, so I decided to stop by for a few and say hi."
"Well, you said hello. Now…:
"Aang, can I have some gum." Katara said.
Aang's jaw stopped chewing. "Uh…sorry. I am all out." He said.
"I didn't know you chewed gum."
"I actually just started." Aang blushed.
"Really? When?" Katara asked.
"When they started putting garlic in the school soup." He said.
Toph giggled.
