"Aah! What just happened?"
"The power went out."
"Well, duh, thank you, genius."
"You are the one who asked the question."
"Hold on."
"What are y—careful, Harada-san. I do have furniture."
"Oww... yeah, thanks. You're five seconds too late."
"You came in when the lights were on. I did not think it was necessary to point out the fact previous to your walking into the table. Clearly, I was mistaken."
"Yeah, yeah, shut up... Huh. It's not working."
"You flipped the light switch."
"... So?"
"The power is out, Harada-san. Flipping the light switch is not going to change that."
"Well, I was just checking!"
"Of course."
"Don't talk to me like that, Hiwatari-kun."
"You are the one who checked the light switch. And walked into the table."
"Hmph. Rub it in, why don't you?"
"Hmm. This only happened after you arrived to work on the school assignment... maybe you should leave and then I will check the lights after you're gone."
"I didn't jinx your house!"
"We could always check."
"Jerk. When I said rub it in, I didn't mean literally."
"You were the one who begged me to put off working on our school project until after the sun set so you could 'use the daylight to—"
"Okay, I am leaving now."
"Watch out. I have a door."
"HIWATARI-KUN!"
