How can these things stay alive?

Every flower that was ever been there follow the same arrive, would stand in a vase near a window, looking so beautifully. By the next week or so, they die. Now that was entertainment : the dying part. they arrive in the same fashion , but die petals would fall out, leaning on its side. Some would be burnt to a crisp by the strong rays of the sun. Others would simply drown like this one. It was given too water , the only thing besides for sunlight to survive. it was the one that kill it. Angelica was a little bored of the scenario but there wasn't much she could injuries would take at least another week, meaning another week lying on the hospital bed and taking rehabilitation of the time she sleeps and think about the feels of her gun in her hands. She thought about cleaning it and disassemble just to assemble it again. She thought about the smell of gunpowder in the air after firing it : you know the simple things. Today she decided to take it easy mentally. She was done with her classes for the day and she was lying on her bed but her mind was dancing around. She was tired and closed her eyes. She didn't dream or anything as she didn't have the time. Just as soon as she closed her eyes, she heard footsteps from the door going into the room. They come to a stop, possibly to check if she was sleeping. They continue their way to where the flower struggle to was sounds of tore paper . Angelica heard it before : that was the sound of someone replacing the dying flower. She was curious as she never place the face to the act. She imagine it was Triela, Henrietta or even Marco. She didn't want to guess anymore, she wanted to know. She opened her eyes to see a girl around her age, maybe younger. She have blonde hair long to her back, in pigtails. She was wearing a blue blouse that fit nicely on her figure. She suddenly turned around to walk away. Angelica and she made eye contact. Angelica noticed she have green eyes but there wasn't very warm. Nothing about her was welcoming yet she delivered flowers to her. She simply walked out the door without a word. Angelica turn to the new beautiful white flower.
