I'm sorry to hear about your grandad Miso. I hope he passed away peacefully.
Sadly, I don't have any more of my grandparents. They were all WW2 vets as well. Granma lived in Stalingrad in 1942. Their whole family escaped on a tiny rowing boat across the Volga river at night when the city was being leveled to the ground.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
