Something Dreadful...

I'm feeling very unhappy now.. feeling so down..
My favourite hamster(greyie) has just passed away today..
Today, early in the morning, I woke up and walk past the hamster cage
As usual, I saw greyie moving.. it seems rather weak or tired..
I was thinking in my mind... is it ok..? it just doesn't seem right.
Last night, I came back home, played with it for a while.
took it out from the cage.. pat it gently.. And suddenly I realized something, it was quite weak at that moment, moving slowly.. and it actually used to be a cute lively chubby hamster.. But that night it was different, I quickly fed it with some food.. but it does not want to eat.. I was worried.. didn't know what's wrong with it so I left it alone..
and I started shouting at my sister, she was always not at home to take care of her three poor hamsters.. told her off and she doesn't seem to care.. always on the phone..
When I came home from work just now, and realized that greyie was gone. I felt so unhappy.. Because when I'm alone at home it used to keep me company. I won't feel bored.. It was like my closest kin or friend.. But now it's gone....
