Those soft and comfy things that were once filled with feathers to make them fluffier. They come in all shapes and sizes, some even have really fancy designs that are usually just used for show.

You sneak up behind your sister, armed with a pillow. She was too focused on the tv to notice your approach. Smiling to yourself you swing the pillow at the side of her head.
"PILLOW FIGHT!" You shout at her.
She jumped up, startled and started shouting at you. You just laughed, wishing that you had filmed that, because her face had been priceless. Lost in thought you were oblivious to the pillow now being swung at your head.
It hit you, "oof," you say as you fall forwards.
"Challenge accepted!" Your sister yelled back.
You started laughing again and swung the pillow. She dodged and tried counter-attacking but missed completely. Then you did a fancy forwards roll and hit her with the pillow. In turn your sister pretend fell backwards and hit you with her pillow. You threw your pillow at her, then tackled her.  You both tumbled to the ground, and Your sister grabbed Your thrown pillow. She then hit you with your thrown pillow, and started tickling you. Laughing even harder you rolled away, and your sister laughed as well.
"I guess it's a tie," she said.
"Don't worry, I will win next time!" You reply.
"Funny, I was about to say the same thing," your sister counters.
Then you both start laughing again, settling down to watch whatever was on tv.
The End

(A/N) it has been a while since I've been in a pillow fight. Please continue to have a nice day 😺. (I have typed in 'have a nice day 😺' so many times that my tablet has it saved as one of the first suggestions that pop up while typing.)
