Fighting:

Italy opened the door for Germany who was carrying all the groceries, and locked it behind him. He followed Germany into the kitchen and helped him put the groceries away. Italy pulled out a few ingredients he would need to make dinner while Germany cleaned the living room. When dinner was done, they ate, and cleaned up the kitchen. All in silence.

Italy and Germany sat in the living room, Germany reading a newspaper, and Italy drawing a picture. Italy waited for Germany to say something, but he hadn't said anything since they got home, and it was starting to worry him.

Finally, the tension was too much for Italy to handle, and he asked, "Germany, what's wrong?"

Germany looked at Italy, then back to the newspaper. He muttered quietly, "Nothing."

Italy was confused, "What do you mean? It seems like somethings wrong; you just stopped talking all of a sudden, so you have to be upset over something… What's upset you, Germany?"

Germany muttered, "Like you don't know." without even looking at Italy.

Italy was even more confused, "What? I… I don't know! That's why I'm asking! You just said nothing.. And now you're acting so… cold."

Germany stood up from his chair and walked upstairs. "Hmm. I wonder why."

Italy ran after him, "Wait! Germany! Where are you going?"

Germany didn't turn around, "Upstairs, is it not obvious?"

"But… but…" Italy started, "Now you're avoiding me! What's wrong? Stop acting so cold!"

"Stop acting like you don't know what's wrong!" Germany shouted.

Italy was taken aback by the Germans sudden outburst, but then matched his shouting, "I'm telling you, I don't! What is it? What did I do?"

Germany kept walking up the stairs, and Italy kept chasing him, "Germany, stop! You can't just.. run away from me! You can't run away from this conversation!"

"Since when are you one to have a problem with running away?" Germany walked into their bedroom and closed the door behind him.

Italy opened the door and walked into the bedroom. He sniffled, "Wow, low blow Germany … are you going to tell me what's wrong with you yet?"

Germany sat on the bed facing away from Italy, "If you don't already know then that's your problem."

Italy sighed, "I don't know if you won't tell me! What did I do?!"

Germany glared at him, "You can't possibly be serious. You don't know why I'm so upset with you?"

"No! I don't! You just came home and said nothing and started being cold towards me for no reason!"

"No reason? No reason?!" Germany spun around quickly, "You can't possibly say that your significant other flirting with another right in front of you as if you don't even matter is no reason to be acting cold!"

Italy was quiet as realization set in and he realized what Germany was talking about. "Th-that?! Germany, are you seriously upset because I spoke with a woman in the grocery store?!"

Germany stood up and faced Italy, "You weren't just speaking with her, you were flirting! And right in front of me, too! Do I really mean so little to you that you have no problem with flirting with someone in front of me?!"

"No!" Italy shouted, "I mean, of course you don't mean little to me! I love you more than anyone else!"

"Right," Germany said, reverting back to his cold demeanor, "Well you have an interesting way of showing that." He walked out of the room.

"Germany, stop!" Italy followed him, "You can't be jealous of everyone I talk to!"

"I'm not jealous!" Germany shouted, "And much less of everyone of everyone you talk to! But the people you flirt with, I suppose I have a reason to be jealous of!

And it's not just this one instance Italy! You do this so often, you act like I'm not around or I don't matter, and you flirt in front of me! You're making it seem like I'm not important to you, or you're so unsatisfied in this relationship, that you'd rather be with someone else! And if that's the case, then maybe we shouldn't be together..."

Italy could feel his heart breaking in his chest, "N-no! No, Germany of course not! No, there's no one I'd rather be with than you! You are very important to me!

I… I'm sorry. I'll admit, I do act flirty with others, but not because I'm unhappy with you, or I don't like being with you, or I'm trying to make you jealous. I just… it's the way I come across, I suppose. But I'm sorry, Germany, I really am... Ti prego, perdonami…"

Germany turned around with tears in his eyes. "I just… I wish you would stop… I'm sorry for not telling you what was wrong, and acting cold…"

"Of course, I'll stop," Italy said, "I'm sorry for not considering how you felt. Promise to tell me if something's wrong?"

Germany nodded, "I promise."

"And I promise consider how you feel, and stop being a flirt, okay?

"Okay."

Italy pulled Germany into a hug and Germany hugged him back. They stayed there, in each other's arms, for the longest time, even when Italy felt Germany's shoulders begin to shake, and the tears that had built up in his eyes were shed.
