I believe with us many no longer count with the childeren to visit them. They even make excuses why the (grand)child can come over and the active ones simply leave and no longer wait. Waiting and hoping they did their entire life.
And those in elderly homes wait the entire day for someone to help them put on their socks, cold tea, food served that has been cooked hours ago and with some luck they have a robot cat keeping them company.
I wouldn't be capable of doing something like that, to think that my parents dedicated so much time and effort to raise me already makes me feel grateful, and everything I could give them would be little, there are very ungrateful people in this world, which by the way is getting worse, all we talk about is war and death
