At what point does Grandpa feel lonely?

When Grandma died and his children didn't have time to come back to see him often, Grandpa was most lonely when he was alone. Sometimes I just see him sitting alone in the yard, and I don't know what he's thinking about, but I just keep sitting there, and it hurts so much to look at him, and I can't hold back my tears, and I want to spend more time with him.

When Grandma was alive, Grandpa could still have someone to talk to, but after Grandma left, Grandpa has been so depressed. He doesn't know how to play the cell phone, and he doesn't have any special hobbies. I would like to tell Grandpa to enrich himself and have fun in life, calligraphy, photography, square dance, go to the senior university to make some friends of the same age, and to expand his interest in life.

I know that the company of family members can reduce the loneliness of Grandpa, so I spent 20 minutes on the phone with my mom every day, came to talk to him whenever I had time, and bought him a lot of green plants, hoping to bring some changes to his life.

Grandpa also slowly learned to enjoy his time by himself: on long winter nights, he would make a little dumpling filling and noodles. He would sit in front of a small stove and boil a small pot of water. When the water boiled, he would wrap up a dumpling and put it in the pot. When the dumpling was cooked, he would fish it out and eat it slowly, and then he would wrap up the next dumpling and put it in the pot to cook it. I'm not sure how much I'm going to be able to do, but I'm sure I'm going to be able to do what I'm going to be able to do.

My mother and I taught Grandpa to play with his cell phone, he said he was not interested and could not learn, so my mother and I bought him a radio, which downloaded a lot of Grandpa loved to listen to the model opera and revolutionary songs, and slowly Grandpa also learned to operate the radio, often cut the flowers and plants while listening to their favorite model opera, it looks not so lonely.

Seeing Grandpa slowly out of the darkness, began to take care of flowers and plants, no longer so much to themselves, my mother and I are incredibly happy, think Grandpa seems to have changed a person, want to say to Grandpa, dear Grandpa, we will always love you.
