My selfless grandad who is terminally ill

Hi my name is Adam and I am 14 years old. My grandad has been recently diagnosed with bladder cancer and it is rapidly spreading. He may not have long left and everyone who knows my grandad well, will tell you what a lovely man he is. It is important to me that he receives the best gift from me before he goes as a thank you for being the nicest man I know. Some of the funds will be used for a gift and the remaining money will go to St John’s Hospice where he is currently housed.
