Did you notice how strange your sister's been behaving?

"Well, hasn't she always been a little weird? Don't think too much, Dad."

The truth is, I never really noticed. Worse, I never paid attention. I'm always too busy with my own life, that I always feel more important and interesting than hers, I lead the life of a more popular kid at school afterall, compared to her. Have I been such a bad sister?

Maybe it's about time to step up.

That night, she suddenly started rambling in her sleep, started off as murmuring but it beame louder and noisier until she suddenly sprang up and straight up heading to the door.

"Where you going?"

She only shot me a glare, her eyes were blood red that I was too chocked to say anything.

I wanted to follow her, but I couldn't move.

The next morning, she was soundly asleep on her bed. But something didn't look right. I couldn't point out what.

"Sis, where did you went to last night?"

"Last night? nowhere."

Was she dreaming then? Sleepwalking?

"Oh...that? I went out to have dinner with my lover."

Dinner? It was past one in the morning. And since when did she have any lover?

"He's having a party tonight, would you like to join us...sis?"

I wanted to scream 'no', scold her or just shake my head at her sinister smile. But it was as if I had no control over myself, strangely.
