Nor do I read or understand French. But plugging it into a translator comes up with this....
R.I.P. dear grandfather loved .. : '(
Today you have left us for a better world without suffering .. I hope you're well up there. Because you see me suffer so much heart was breaking. Is not easy to see you in this state, nor to see you go. You were everything to me, I still can not believe you're gone for good. It is so difficult to live without your presence. I'm bored to spend a lot of good times with you. I would like to thank you once again for all the things that thou hast apprisent and the values you gave me transmitted over the years. Someone as special as you do not end up all over the place and I am very proud that you are part of my life. I love you so much my grandfather loved and forever!
My sincere apologies Jacques if this is not accurate text.
God bless
