I wish death on my grandpa
Are you being serious? Why do you wish that your grandpa would die?
Some of the things I've wanted for a long time
Really, your grandparent? I think that it is wrong to wish death on anyone, but especially your grandparents!
I didn't get the gifts I want and I hate him.
There is no reason to want your grandparents to die. One day he really will die and you will miss him.
