"Yeah," Sora replied, cracking eggs carefully. Nothing more traumatizing than accidental eggshells in your food. "How should we decorate it? Write on it?" They couldn't just leave it blank, that was too boring.
Tsuna was seeing it, but he sure wasn't getting it. "Hey Gokudera, can you show me where the bathroom is?"
Sora snickered. "Can't you go potty by yourself Tsuna?"
Tsuna turned red and punched his brother, who actually made a small 'ow!' at it. "I don't know where it IS, dummy." Which actually meant he wanted to talk to Gokudera and needed an excuse to leave the room with him.
