Its time to let go

I only have known you for four years,
I wish i had known you longer,
I cant let go this soon,
It fells like i just meet you,
Your my grandpa and i need you,
But i guess god needs you more,
Every one is saying i should just let go,
But what you and me had when i knew you was special,
I want to cry when i see you but it wont come out,
I guess god needs you more than i do so i will try to let go.
