How did things end up this way?

Chapter 7.

A/N: This is a taster for the full chapter. I'll do the full chapter later.

A couple of days later.

It's Saturday morning and I'm woken up by loud banging on my front door. Whoever it is, they're certainly keen, it's only 9:30am!

"Alright for fuck sake, keep your hair on, I'm coming!" I shouted through the door.

I opened the door and was shocked at who was standing there.

"You?" I answered, clearly in shock.

"Yes it's me, you do remember who I am don't you?" The person answered, sarcastically.

"What are you doing here?" I questioned.

"I've come to see you" They sneered.

"Well, I've got nothing to say to you, so can you please leave?" I asked them.

"Who is it Tula?" My mum called from upstairs.

"Oh no-one, it's just one of my old mates!" I shouted back upstairs.

"One of your old mates eh? I take it Mummy doesn't know what a cow her little "princess" is?" They snarled at me.

"No she does not and I would like it to stay that way!" I hissed at them.

"What are you going to do?" They laughed at me.

"A lot more damage than you care to realise! Now fuck off and don't ever come back!" I warned them.

"Oh I'll go for now, Tula. I will be back though and when I come back, I WILL take my revenge on you for what you did because don't you think for one second I've forgotten what you did! I'm going to smash your world into tiny pieces just like you smashed mine, you little bitch!" They threatened me.

What had happened? What had Tula done? Who was this person and why did they have such a grudge against Tula?
