Better Little Sister

How much taller is your little sister?

I'm taller, actually

About a head taller

I come up to her chest

I'm like a child compared to her

I'm shorter than her toes

How much stronger is your little sister?

I'm stronger

We're about the same

She's much stronger

She's so much stronger, I can't even move her

How much smarter is your little sister?

I'm smarter

We're about the same

She's a grade ahead of me

She's several grades ahead of me, and makes straight A's

Is your sister...

Nice about being better?

Cruel about being so much superior?

Or does she force you to worship her as a Goddess, flaunting her power?
