I'm sorry to hear about your loss Ahmed. My sincere condolences.
I hope you got the chance to take a proper farewell. I'm still kind of annoyed that I didn't get to take farewell of my grandfather, for some reason no one thought it would have been pertinent to tell me about his deteriorating health and hospitalization while I was working abroad. Dealing with the loss of my grandmother was easier in that sense since I could visit her quite a lot during her final weeks.
