Do not argue with small-minded people

Being older does not necessarily make someone an adult.
Even if someone is old, if the trajectory of their life
is not worth emulating and they lack character,
I may treat them with outward courtesy, but I do not consider them an adult at all.
As one ages, they should possess dignity, composure, and tolerance.
However, a narrow-minded, small-minded elderly person who is less patient than the youth,
unconditionally insists on their own opinions, loses their temper, and stubbornly clings to their own position—
it is best not to bother debating or exchanging views with them.
The right answer is simply to say "Yes, yes" and let them have their way.
