Chapter 3- friends and Family

~almost 1300 (1:00 pm)~

~Kaiden's POV~
Yawn. Ugh, go the FiretrUCK away sun! I'm not done sleeping. I think as I roll over, suddenly I hear someone yell "WAKE UP KAIDEN!!!" while jumping on my bed. I turn around and see that it's just Jc,that's when it hit me! I screamed out of fright when I realised that I wasn't in the bed I've known for so long.
I guess I screamed so loudly the other guys rushed up to me and Kian asked "what's wrong? are you ok Kaiden?" I blinked a few times letting my memory catch up and nodded my head yes "yeah, I was just a little scared I wasn't in my normal bed. Sorry if I worried you guys" I apologised.
"So, just out of curiosity, how long have you been in the orphanage?" Sam asked, Kian glared at him. I looked at him letting him know that it's ok. Then I said "I've been in orphanages for seven years, and in this one for almost five years." Kian looked at me with what I think is worry in his eyes. Then I get out from the covers and stretch. Completely forgetting that I'm wearing a tank top and shorts.
~Kian's POV~
I'm down stairs talking to the guys when Jc goes to wake up Kaiden, after a minute I heard her scream, so we rush up the stairs nearly tripping. Once we get up I ask "what's wrong? are you ok Kaiden?" She blinked a few times and nodded her head yes "yeah, I was just a little scared I wasn't in my normal bed. Sorry if I worried you guys" She apologised.
"So, just out of curiosity, how long have you been in the orphanage?" Sam asked, I glared at him. Kaiden looked at me letting me know that it's ok. Then she said "I've been in orphanages for seven years, and in this one for almost five years." I looked at me with worry in his eyes. Then She gets out from the covers and stretch. Wearing a tank top and shorts.
I notice scratches and bruises all over her arms, legs, back and stomach.
She noticed we were staring at her and then she suddenly ran down stairs. We followed her out the house and we ran back to the orphanage, Kaiden jumped the fence to the back with us behind her. She closed and locked the doors once again, leaving us outside. Suddenly she disappears from our sight.
"Where do you think she went?" Ricky and Jc asked "I don't know, but I'm scared to find out. Come on, let's go" we then hop the fence again and go to the front door and knock waiting.
About two minutes later Ms. Peters opens the door, giving us a confused look. "Hello boys" she said opening the door letting us in "how can I help you?"
After explaining what happened, she excused her self and went upstairs. A minute later Kaiden came down stairs with a few more bruises. I hugged her relieved, as soon as I let her go she just walked away. I looked to Ms. Peters again and ask what happened she tells u "she likes physically fighting with the boys, she gets bruises from the fights. But yet, she has fun and continues fighting with them" I nod to her and we all walk out to Kaiden.
As soon as we catch up with her, we stop her and she looks down from us. I kneel down to look at her but she looks away. I sigh and say "Kaiden, we know you fight with the boys at the orphanage. We don't have too much of a problem with it. We just wanna know why" she clenches her fist tighter and says "it's no ones business" she then takes off again towards the orphanage, where the boys are waiting. We walk over to them slowly. The boys form a barrier around her and the tallest one says "go away" in a threatening voice. We stand our ground and say "not without Kaiden" ,another one barks saying "can't you see that she doesn't want to leave us. I bet you don't even know how to take care of her!" "Guys, just drop it. I was adopted, I have to go with them. But I'll be back, I always am. Later" Kaiden says then walk towards us.

What does she mean by that?
