Thanks for all the reviews and ideas and junk! They all really helped :) This one is gonna be a Carlos/Katie one. (brother/sister) I hope you like it!

I don't own Big Time Rush or anything else at all.

The following plot was submitted by Anonymous Skrtle.

Katie sat on her bed, a shoe in her hand, and tears of frustration racing down her cheeks. She was trying to tie her shoe, but she just couldn't do it, no matter how many times she tried. She took the two ends of the shoelace in her hand, and put them together. Why wouldn't they tie? She always watched Kendall tie his shoes and it always looked like he just put the stupid strings together and it was tied. So why wasn't it working when she did it?

"TIE!" she screamed at the shoe as she rubbed the ends together. "TIE YOU STUPID STRING!" She looked up when she noticed someone walking into her room. Carlos was standing there, confusion written on his face, and perfectly tied sneakers on his feet.

"What's wrong Katie?" he asked when he saw she was crying. She glared at him, and his feet, and ignored him. He walked over to her bed and sat down next to her. "Katie, why are you crying?" he asked sweetly.

"I can't tie my stupid shoes!" she yelled. She picked up her shoe and threw it as hard as she could against the wall, which thankfully, wasn't very hard. She sat on Carlos' lap and cried into his shirt.

"Its okay, Katie. You'll get it eventually, don't worry," he soothed. He rubbed comforting circles on her back, and prayed he was doing this right. He didn't usually comfort people, especially not little girls. But he's seen Kendall do it plenty of times. "I can teach you if you want," he offered. She looked up at him, hope shining in her eyes.

"Really?"

Carlos nodded. He got up and got her shoe from across the room and sat back down in front of her. "Okay, just take both strings, and then cross them like this," he explained. "Then, you put one underneath and pull it so it's tight." She did as she was told, and a smile came to her face when she got it right. "Okay, then you make an 'O' shape, wrap the other string around..." Carlos watched Katie copy his actions, and he was surprised that she actually got it right away. "Then you put the other string underneath," he told her. "And pull!"

Katie followed step by step and by the time she was done, it was in a messy knot. But it was close enough for her. She jumped into Carlos' awaiting arms and hugged him.

"Thanks Carlos!" she yelled. "I never knew you could be so smart!" Carlos laughed.

"Well, math's not my thing, but shoes are!" he exclaimed, hugging her back. She giggled when he picked her up and swung her around the room. "You're mine now!" he said in a deep voice, dragging her out of the room.

"No!" she laughed. "No! Let me go!"

"Never!" Carlos yelled as he brought her over to his friends. "She's ours now, boys," he said to them. "We can destroy her!" he yelled. They all laughed, and tickled her.

She had the best brothers ever.

I had no idea how to end this one. I didn't want to end it like all the others with "I love you!" you know? So..I just did that cause I do that to my friend's little brother all the time...

Review? :)
