On his way back upstairs, Jon said to himself, "Ugh, I wish I could just get some sleep without anymore interruptions."
He got into bed and slept.
When his alarm clock went off an hour later, he didn't wake up. The alarm just kept ringing four nearly two and a half hours. When Jon just wasn't tired anymore, he woke up.
Then he heard the alarm and looked at the clock.
8:56
"What the hell? I overslept? School started almost an hour and a half ago!"
He hurriedly got ready for school and ran out the front door.
