Sad for your loss, Ilan. I know how it feels. Lost my dad the summer of 97. He was asleep when I arrived that day, after my older brother had phoned me. A couple of hours before he left for good, he opened his eyes, turned his head towards me, and smiled. Then he turned the other way, smiled at my younger brother (the one I've mentioned earlier on, who's had cancer five times, still never brings it up if noone else does, just goes on in the most positive way), closed his eyes and was gone at midnight.
My mother left six years later. As late as last week I got the notion I should call them up. Felt really glad for a very fast second. Then I remembered. So do us all a favour. Sit down and talk to your parents. Ask questions about them, their relatives and friends, and the way they grew up. Write down the information you get. Which is what I did, when I realized I couldn't talk to my father no more. So my ma gave me answers to everything I wanted to know. Now I can bring the stories to my own kids. Stories of poverty, pride, TBC, and very hard times. It sure has helped me to feel thankful for almost every day I live.
