You should never hate old people, especially if they are a part of your own family. They have gone through tough times to bring us (or our Dads and Moms) up, and now when they grow old and frail, and their body is slowly weakening and shrivelling up, they need someone's support to lean on.
I have seen my maternal grandfather shut himself out of the world once he retired from public service, and keep to himself till his death 10 years back. He was given a bed near the bathroom by my maternal uncle who did not want to take care of him, but was ready to grab his retirement pension money. The guy who saved enough to marry off 5 daughters and secure the future of his 2 sons, spent the rest of his days inhaling fumes from his younger son's bathroom, and staying quiet. He ate whatever was given to him, prayed, and slept. And when he died, there wasnt much fuss either.
Just remember, old people were actually us once. Those guys were young and full of life too, like us. Someday we will grow old also, and when our body starts behaving erratically, and the problems dont solve themselves, we also grow a habit of being irritated at the smallest of things. Our children and grandchildren will be annoyed with us then. "Future is a mirror of thy's present", so even if they are irritating, annoying, pestering etc. etc., they deserve our attention and our love. You give it, so you will get it.
