5TH October 1908. – Austria-Hungary annexed Bosnia and Herzegovina

Belgrade watched Serbia pace around the room.

"You're giving me headache. Stop it.", she said harshly.

Serbia continued, not paying any attention on her. Belgrade sighed in frustration. She hated when Serbia was in this mood. Never listens to anyone, never speaks to anyone, except when she has sudden outbursts of anger that last about a minute. Belgrade frowned at the broken vase that Serbia broke when she heard the news- Belgrade actually didn't know what the matter was, since Serbia threw the letter in the fire and stubbornly decided to keep her mouth shut.

"It was my favourite vase, you know. It's not like it's important, or anything.", she said in annoyed tone of voice, trying once again to draw Serbia's attention.

Silence

"GOD DAMMIT SERBIA TALK TO ME FOR FUCKS SAKE!"

"Bosnia is annexed.", Serbia said quietly.

Belgrade blinked rapidly in confusion. It wasn't because the Bosnia was annexed- everyone could see it coming, but it was more because Serbia's sudden willingness to talk to her.

She stared at Serbia for few seconds, expecting that she will keep talking, but no…

Dear God, do I always have to ask her a million questions before she actually gives me a full answer?

"So, what happened exactly?

"I have to go see Russia.", Serbia said with the same quiet voice, talking more to herself than to Belgrade.

Well, that send Belgrade over the edge of her patience. She stared at Serbia's back as she was getting out of the room. Belgrade's blue eyes darkened a little bit as she was boiling in rage. She stood up and sprinted through the door.

"YOU CAN'T JUST LEAVE! YOU CAN'T EXCEPT ME TO STAY HERE WHILE YOU GO TO RUSSIA AND LEAVE EVERYONE BEHIND, ALTHOUGH YOU ARE RESPONSIBLE FOR THIS COUNTRY!" Belgrade followed Serbia to her room, yelling at her in anger and frustration, her face going red with fury.

"Belgrade, I need you to take my duty until I'm back."

"NO! DO YOU HEAR ME? No way! You're not going to leave me here to mess with this!"

"You'll do well. You did it before."

"Not in the middle of the absolute madness! And even when it was normal, I wasn't happy with it. I'm A CITY. I will mess something up.", she felt her rage slowly fading away, after the first hit. She knew that soon she will calm herself down.

But I don't want to calm myself! I'm right!

"You are smart. I trust you. It won't be for long anyway-few weeks.. Plus, I'm not leaving you in the middle of the war."

Belgrade closed her eyes. She felt the adrenaline going away, letting her think properly.

Yeah, I'm right, she shouldn't leave me to mess with this. But at the same time- I don't want her to do something idiotic and stupid while she is in such a state of anger- and she could do that. I think Russia knows it isn't time for anything yet. And we all know who is the person who can persuade Serbia not to do anything stupid.

"Fine.", she said, carefully watching that her voice still sounds irritated. She didn't want for Serbia to think that she is absolutely fine with this.

Serbia quickly hugged her. "Thank you."

"You better be.", Belgrade muttered in the response.

Austria-Hungary's annexation of Bosnia and Herzegovina caused quite the tension.

Serbia's goal was to unite all countries that were the part of the Serbian Empire and where Serbs live in big number, and Bosnia and Herzegovina was one of them.

Great Britain and France were also not pleased with the annexation, since they saw it as a violation of the Treaty of Berlin.

Russia (surprise surprise) was okay with the annexation, they knew about that it will happen eventually and tried to somehow make it good for them. Russia was the one that calmed Serbia and Serbia quickly back down.
