I

I'm soft but strong
I'm short but long

I'm passionate but lame
I'm smart but insane

I'm beautiful but ugly
I'm aggressive so softly

I'm rich in a poor manner
You're who? It don't matter

I'm sharp but very dull
I'm empty but then again full

I'm funny but serious
I'm quiet but delirious

I'm sneaky but straightforward
I'm bad but I'm very good

I ask, "Who am I?"
I am Gemini
