This chap is simply questions asked, and her replies 

'Would you like to explain how you got to this situation?'

No

'Would you like to defend yourself?'

No

'Would you like another detention?'

Not really 'So tell us why you decided to play this prank,'

A prank? Who said that?

'Do you think we're not good enough to speak to?' That was James' question. Lily smirked.
Do you really want me to answer that one Potter?
'Stop bickering. I'm afraid if you do not stop this nonsense, I shall have to suspend you,' Is that supposed to make me speak? What is it, a new remedy? Dumbledore sighed once more. Perhaps James had rubbed off on her...

'I'm sorry Miss. Evens, but I'm afraid I'm giving you detention until you decide to speak,'

That'll be an awfully long time, and the floors would be scrubbed so much, students wouldn't be able to walk by for fear of blinding themselves,

'Miss. Evens, please stop the rude comments and simply tell us you are sorry or why you are not speaking. Just stop this prank and-...'

Lily jotted down a note a left the office angrily, dropping the not behind her.

I'm sorry you do not trust me, but I must be off. I'll go somewhere I'm not punished for being bullied

Dun, dun, dun! What will happen??? REVIEW!
