It's easy, if your avatar is a person, you have to talk like they would.

Ex: If it's Sora, you have to be upbeat and positive.

(And if it isn't a real character, than you can make up your own personality!)

I'll go first:

Asuna?! Asuna!? Where did Asuna go?!

Um,I really must be going now.

Where did Asuna run off too?! Seriously!

*Snarls* Who dares disturb my slumber!?!

Why I would never do that ever!

*Blinks* Oh, it's you 'ttebayo.

Anyone want to travel in my snog box?  I have fish fingers and custard!  LETS GO CAUSE A PARADOX!!
