Lights:
The lanterns were set up on the training grounds and Kakashi held the last ones, post already driven. He sat down to wait.
A couple of hours past and the sun set before Iruka showed up. He gave Kakashi a sheepish smile and offered him a hand up. "Sorry, Kashi, Izumo was late, really late."
Kakashi took his hands and stood up. "Mah, it's fine. Nobody is going anywhere anyway."
"At least you were here to keep them company." Iruka leaned over and kissed Kakashi's cheek. "I hope you're not telling them any tales on me or I'll have to return the favor," he teased.
"On my life-" Kakashi smiled and pulled out a scroll, "-I haven't told them anything they couldn't have guessed."
Iruka punched him in the shoulder, took the scroll, and unrolled it. "Yondaime-sama, how is it he was your student and still turned out this way?"
Kakashi pulled a paper lantern out, set it on the hook and then lit it. "I learned from the best."
"Besmirching your sensei's name..." Iruka tsked, shaking his head and tying the scroll to the bottom of the lantern.
"I'm not 'besmirching' anything if I'm telling the truth," he laughed, pulling out another lantern and scroll.
Taking the scroll, Iruka rolled his eyes. "Uh huh... your 'version' of the truth I'm sure. Be good and hang up your lantern."
Kakashi laughed and let his eyes drift over the lanterns, a sense of contentment filling him as the lights flickered. Even if it was only the second year of Iruka helping him with this tradition it already felt like it was itheir/i tradition. Some day hopefully, preferably long after they were old and Iruka had gone grey, their lanterns would still stand next to each other.
