Sorry to hear, hope for the best though. I had a friend whos mother had a similar medical emergency and she pulled through fine and I hope your grandfather does too!
My deepest condolences rest with you and your family, Marco. Be sure that he is in a much better place as this is a cruel world. If you need someone to talk to, you have me on Steam buddy.
Forgot to say , he's not dead (yet) , there's too much blood in his head, he can't eat solid food, he can't really speak, he can't even move , and only his arms and head , but the worst part about this is that he will never be able to get up from his bed, he's stuck 4ever in his bed.
