Sory to hear that, dude, I feel for you

I remember when my grandfather died a few years ago, he was in Italy and I couldn't take the time to go see him one last time... When I went back there after he had died, it felt so strange for him not to be there, and even 7 years later, I still think of him and miss him. But make sure to keep the good memories especially, at least you'll be a little happier when you think of him
