Ya know, when ever I lose something dear, wether from misplacing it, or breaking it, like a stuffed toy or some accessory, I feel like... I lost part of myself...
And then I feel angry at myself and terribly sad, and even guilty for loosing it. And then when my parents say something like,
"Oh, don't worry! We'll just buy you a new one." it only worsens my feelings, and then I say,
'No! It'll never be the same!' 
Now I'm older, so far I haven't lost anything important or valuable, but I still carry the feelings of the little girl I used to be.
