The end of the World

What?Why?How?

"Oh my gosh!" We both screamed at the same time. We both walked over to each other slowly, we happened to be identical!! "Why?How? I don't even have a sister! Especially not a twin sister!" I screamed. "I didn't either!! I lived with my mom and dad I was an only child!" Kailee told me. We both took another good look at each other to make sure that weren't hallucinating. "Who are your parents?" I asked. "Christian and Hank Alexander, but my mom uses her other last name a lot" She tells me pulling out some water from her bag on the ground. "What's her other last name?" I asked curious. "It's Perez, why?" She tells me confused. "Oh my gosh!!! My dad's last name is Perez! " I screamed.
"That could be a coincidence, or..." She said trailing off. "No seriously, my name is Jordyn Perez. Now we know this is true, but how could your moms old married name be Perez but my dad's last name is Perez. There only could be one explanation.. Our parent used to be to be together!!!" I screamed so confused. "Then my dad is my step dad and your mom is your step mom. When your dad and my mom were together they had us, and they had been lying to us for our whole lives!" She told me starting to get angry. "They must have split up right after we were born because I don't remember anything about that," I told her starting to get angry to. We both were angry at that point, "Why would they do this to us?" I asked getting angrier.
"Why???" I screamed, "Why?!!!" I picked up and rock and threw it at the building. "I don't know, if only we could ask them" She tells me ducking from the next rock I threw because it almost hit her in the stomach.
"Ok, so we should stop talking about this and find a place to stay for the night" I told her grabbing my bag and getting ready to go. "Ok let's start walking" She told me starting walking the opposite way I came.
Kailee and I spent the next four months or together, until....
