You texted me first

Derek ---> Stiles

Derek:
Are you in class?

Stiles:
That depends...will you keep texting me if I was?

Derek:
No

Stiles:
Then no, I'm not in class

Derek:
Seriously?

Stiles:
Seriously.

Derek:
I don't even need to listen to your heartbeat to know that you're lying

Stiles:
Oh come on Derek! I'm in history class and I already know this shit with Hitler and what happened under World War II so please, give me some attention

Derek:
Fine

Stiles:
Good, so what do you want? You texted me first (which almost never happens)

Derek:
You know that I was at the school?

Stiles:
Well yes, Isaac told me. What were you even doing here? And why did you have to break my locker?

Derek:
Yeah sorry about that

Stiles:
Care to explain why?

Derek:
Not really

Stiles:
I find your lack of vocabulary...interesting

Derek:
?

Stiles:
Oh sourwolf you know what I'm talking about. The only words you seem to know are "shut up" or "no"

Derek:
What about "I'm going to rip your throat out...with my teeth?"

Stiles:
How could I forget?

Derek:
Shut up

Stiles:
See what I'm talking about?

Derek:
True but you know that I don't like to express my emotions

Stiles:
I know. Instead you like to throw teenagers into walls

Derek:
No need to be mean Stilinski

Stiles:
You love me

Derek:
Yeah I guess I do

Stiles:
See! The grumpy alpha can actually show something more than anger

Derek:
Stiles?

Stiles:
Yes my lovely Dearbear?

Derek:
Shut up

Stiles:
Make me 😏

Derek:
You're in class. Focus.

Stiles:
I can't

Derek:
Why?

Stiles:
Because of my A.D.D and the hot werewolf who keeps texting me

Derek:
I don't know what you're talking about but that hot werewolf of yours seems nice

Stiles:
Not really. He likes to throw innocent teenagers into walls and threatening them with ripping their throats out...with his teeth

Derek:
You love me

Stiles:
How could I not?

Derek:
True. I'm irresistible

Stiles:
Who are you? And why are you texting Stilinski during his class?

Derek:
Ehm, who am I talking to?

Stiles:
This is Mr. Harris. Stilinski's history teacher. Which class are you in? So I can let your teacher know about this, and take your phone away

Derek:
Actually I have already graduated from school sir

Stiles:
Very well. Since I can tell that you are pretty close to Stiles, could you inform Mr. Stilinski that he can come and pick up his sons phone after school?

Derek:
I will

Stiles:
Have a nice day

Derek:
Same to you sir

Stiles:
And please, don't text Stiles again while he's in class. He need to concentrate

Derek:
I promise

Stiles:
Very well.
