[ WP ] Write the witness statement of an inanimate object used in the committing of a crime

All day long, I sit still. Bathing in the sunlight, very little friction ever comes my way; and what little friction I do get... it's always pleasant. Always full of life, I hear the children screaming and yelling. Shouting `` I'm going to get you!'' At each other, or `` no you're not!'' For a response. 
 
 Of all the shape-shifting items in the world, I have it the best. If I get dirty, someone cleans me up. If they have people over, I enjoy making them happy. If it's gets cold, they cover me up. I have it made. 
 
 Wait!? What's this??? who are these people??? What are they doing to my family!?!? No... no do n't play with me, it's night time... let me sleep under the stars. Tommy, go back to the surface, you're not meant to be down here for so long... tommy. Tommy!!!!! Get up Tommy, move your hands, legs, feet, ANYTHING! 
 I try to hold him, I surround myself around him. I will protect him now, until help comes around. Tommy was a good kid, so much life to live... I will make sure to tell the mortuary my side of the story, I will help tommy. Tomorrow. Right now, I just want to comfort him. 
 
 Here Tommy, sleep on top of me... I'll be the best bed you have until help arrives. 
 
 The family, now comes down the stairs for breakfast. all smile and giggling, I do n't want to break the bad news... but I have to. Help me out sky, I need your reflection.I need them to look outside with a good feeling. perhaps the last good feeling they will have. 
 
 I hear the scream, and the mother comes running, falling to her knees at my side.the father, abruptly moves me out of the way, while I, forgiving, allowed him too. Question to be remained, and the sirens comes closer. 
 
 Help is on the way Tommy, I'll never forget you. 
 
 
 ( I'm on my phone at work, if I get enough up votes and or comments, I'll add onto and edit it )... should be easy to guess, but what am I?
