Recently, my grandfather (my mother's side) of 86 years of age left to Mexico after a huge argument with the rest of the family. Don't know what exactly could have triggered such a scream fest, but it got physical, and both my grandfather and father (who tried to stop him) were hurt, although my grandfather's injuries are unknown to me. That man had developed something that reminded me of King Saul; letting himself slowly lose his sanity and becoming a terrible person, physically and mentally. He stopped being grateful for the sacrifices that his family (including an uncle of mine) made just to take care of him and my grandmother and making sure they were healthy. After a while, he took to nagging and complained about everything, even about our family, until the incident I mentioned above.
That man is dead to me, and will remain like that until he fixes his attitude. As I type this with enraged fingers, I will let others know that no way in hell will I let myself be called his grandson. What little sympathy and respect I had left for him is gone, reduced to atoms (no, I have not seen Endgame). And, while I would never wish calamity upon any foe of mine, I hope he knows that he needs to be with his family; that it's for his own good and for his safety.
