Mabel had been acting strange lately. Ever since we visited the Institute of Oddology, she had been visiting Robbie on and off. Not only that, but sometimes she would come back dressed in all black and wearing makeup that would put a raccoon to shame. I decided, as her brother, I would confront her on this.
"Mabel, what is with you visiting Robbie all the time?"
"What does it matter, Dipper? Robbie and I are becoming friends."
"I thought you said he was a jerk, like the human version of rat poison."
"That was when I was younger. He's changed."
"Yeah right."
"Its true! Beside, I..."
I saw Mabel blush and look away.
"I don't believe it." I said. "Did he hypnotize you too?!"
"No! It's not like that! We're just friends."
"Mabel, you're 17 and he's 21; that's statutory rape!"
"He's never touched me in that way. Besides, we're both going to be 18 soon, so why does it matter?"
"It matters to me if my sister is going out with a monster."
"Dipper, we've battled monsters in the past and he's not one of them. Why can't you ever look past the surface?"
"Why can't YOU be smart for once?!"
Mabel gasped. Tears slowly started to form and I saw she was about to break.
"You know Dipper, as of now, we're no longer siblings."
Mabel left the room and I could hear her crying. I started to wonder if I was in the wrong.
