Disclaimer: You must be terribly mistaken, I do not own Hetalia. However I do own my OCs, not the actual countries though.
No nation created from the ending of World War I was born on that day. To put it simply, they lived in their parent/parent's house until that day. After all, how else would they have their culture. They didn't forget everything their parents taught them. Now, having said that, let's get acquainted with Czech and Slovakia. Austria and Hungary's children who represented Czechoslovakia for a short time but are now Czech Republic and Slovakia.
The two young nations were "chibified" when they lived in Mr. Germany's house with their parents. The two had big green eyes and dark brown hair. Similar to Feli and Romano, they had cowlicks, or ahoges as Japan called them. Czech, being West of Slovakia had an ahoge on the left side of her head. Slovakia, being East of Czech, had an ahoge on the right side of his head. This made them much more identifiable as young children who wore the same clothes and looked virtually exactly alike.
Now that we are through with the introductions, let's take a peek into the day of Czechoslovakia.
Oh boy, what's this? Miss Hungary is telling the duo a story! "Because Czechoslovakia technically came out of Austria, you should call him "Mama" and you should call me "Papa". Do the two of you understand that?" The older nation asked her children.
"Yay Papa Hungary!" Czech cheered.
Slovakia on the other hand simply pouted a little. Hungary, with the blood in her veins boiling for bloodshed, pulled out her frying pan. "Slovakia, I couldn't hear you." She said with a menacing grin on her face. Of course, she would never hurt her children in such a way, especially because they were still technically still a part of Austria-Hungary.
Slovakia pouted and crossed his arms childishly. "Ja, Papa, ich verstehen." He muttered.
It would seem that, because of their placement on the map, Slovakia stays closer to Miss Hungary and Czech tends to stay close to Mister Austria. Or rather, Papa Hungary and Mama Austria. Mama Austria made sure that they were both very educated by him, considering they were his children after all. When they were big enough, he started them both on playing the piano and claiming that famous composers were Austria, much to the house owner, Germany's, misfortune.
Alright, sorry this is so short, I'm not sure what I'll be doing with this. Hopefully they will grow up fast! I will be centered more around Czech Republic though, and will call her Czech for short. I might have some of this based off of actual history, but I'm not too sure, if I do, it won't be too accurate. This story is for fun.
Slovakia pouted and crossed his arms childishly. "Ja, Papa, ich verstehen." He muttered.
Yes, Papa, I understand.
I'm not too sure if that's correct. My dad and grandparents have taught me some German, but not much. I don't know how to spell it all all, so I googled it. I really apologize for any incorrectness.
