It had been an hour since the shrill cry of the alarm clock had been silenced by a single punch. As the last bits of ringing died on the floor, small room fell back into silence for another solid hour, while owner of the punching hand dozed off, unaffected by the brutal act. That until the loud buzzing of the phone filled her ears like a nest full of wasps and caused her to let out a loud groan as she reached for the phone to yell obscenities.
"WHAT?"
"Ruff, it's nine. Get up."
"Go to hell."
"RU-"
The call ended before he could even say her name and he rolled his eyes at the screen, sighing and praying for patience, wondering why this had become his duty when he never ever signed up for it. Tuffnut was snickering next to him, enjoying the fact that he no longer had any responsibility towards when his sister managed to get her ass out of the bed. The short guy squinted as he called the number again, bracing himself. He could almost see Ruffnut waking up once more, ready to devour him but he also knew she would be more pissed if she ended up missing the exam.
As soon as he heard a voice at the other end of the phone, he yelled in panic.
"Get up already!"
"Leave me alone, freak-"
"Ruff, you have an exam in half an hour!"
"Your words mean nothing."
"If you don't get up, I'm telling Tuff what you've done last week."
"…I'm up."
Tension was rising on his shoulders; he nearly threw the phone on the table and reached for his coffee like it was the last life jacket.
"Every. Morning. I swear…" Even finishing his sentence felt like too much effort. Tuff was still grinning, this time more curiously.
"Dude, what did she do?"
"You already know."
A/N: Little bit of modern AU. Ruffnut is not a morning person. I guess it was non-heionus' headcanon that Snotlout was the early riser and I am totally on board with that.
