I was watching episode 241 and just wondered how Guy was able to just walk into Kakashi's house. Plus Sakumo was alive at that point so it fits.
The small figure stealthily jumped throught the window of the large compound. He concealed his chakra as best as a young ninja could and quietly walked through the guest bedroom and cracked the door open. As he peeked around looking for his soon to be rival, he sensed noone on this side of the house.
The young boy jumped to the ceiling and crawled to the otherside of the house hoping to find the ninja he was looking for. He peeked into one of the open doors in the hallway and saw a clean room that wouldn't be taken for a six year old's room save for the small stuffed puppy that was laid on the pillow.
The small ninja kept on going finally sensing a person in the kitchen. He rolled onto the ground not making a single sound. He quietly slid open the sliding door and jumped in front of the other figure shouting for a challenge before realizing who he was standing in front of.
"You, you're the White Fang."
"That's what people call me. So who are you and why are you in my house?"
The bowl cut haired boy simply stared at the silver haired man for what seemed like an eternity. Suddenly the man poked him in the forehead.
"Hey, I asked a question kid." The boy still stood frozen from meeting his idol.
"Umm... I- I'm Guy." Realization hit Sakumo as he remembered Kakashi complaining of this kid yesterday. At first he laughed it off, but if the kid was going to break into his house constantly than he was going to have to lay down some rules. Either that or reset his home's defenses, which he wasn't looking forward to.
"Guy huh? So why are you in my house?"
"I was trying to challenge Kakashi and become his rival..." Guy started to look down and become uncharacteristically shy.
"Oh I see, well sadly Kakashi isn't here right now." Sakumo said as he crouched down to Guy's level. He knew he was looked up to especially by the young kids in the village so he did his best to be a good role model.
"Where is he?"
"He is on a mission with his sensei right now." Sakumo pointed out to the genin. "I'm happy you're trying to be friends with Kakashi though." Sakumo smiled at the six year old.
"Really! So I can be his rival!"
"That's up to Kakashi to decide, but I don't mind you coming over more often. Just use the door next time. It'd be bad if people learned a genin broke into my house."
"Yessir!" Guy saluted, smiled and gave a thumbs up to the White Fang.
Sakumo smiled as he led Guy out the door. Hopefully he wouldn't have to deal with more weird kids in his house again. Well except for Kakashi.
