How to treat the love of older parents?

Parents of the older generation are ashamed to express their love. They have never said "I love you" all their lives, but they have been doing "I love you" all their lives.

[Heart] Detail 1: Parents have been married for more than 40 years, and the shadow of love can still be found in the details of getting along. My mother has a bad temper. Sometimes when she gets angry, she can lecture my dad endlessly for more than an hour. Father never talks back, but listens silently with an expression of knowing his mistake. When mom is tired of scolding, dad can always pass a glass of water at the right time, then pretend to turn on the TV that mom likes to watch unintentionally to attract her attention, and then the quarrel is over.

[Heart] Detail 2: My father likes to let my mother do the same things as him, such as sweeping the floor. My dad sweeps one side and my mom sweeps the other. And watching TV is the same, even if you don't like watching it, you should stay with my mother. Although my mother often expresses her dislike for my father, she is always honest in words and actions. I was puzzled by this and asked my dad quietly. My father replied, "Because your mother and I do the same thing, we have a lot to say, and so does watching TV. I like to see someone happy with me in beautiful places. Of course, your mother needs such a partner. Although your mother often dislikes me, I am used to it, and it is uncomfortable not to listen occasionally. "

[Heart] Detail 3: My dad doesn't like to call others. As children, we usually call him for less than three minutes, and the atmosphere is too embarrassing to talk. But my mother is an exception. A while ago, my father's foot was empty and his right foot was broken. Because of the epidemic prevention and control, the patient can only stay with one escort, so this important task is handed over to my brother, and my mother can only wait at home. Later, my mother called me and told me that she videos with my father every night. I joked, "Did you call my dad? Talked for a few minutes? " "Soon, just ten or twenty minutes." My mother answered it. I was shocked to hear that. My dad can say that? My father stayed in the hospital for two weeks, and my mother talked to my father by video every night for about twenty minutes. I can't imagine my taciturn father and mother talking so well. My mother once told me that whether a person has you in his heart depends on what he has done. Maybe my dad put love into the details, so my mom can criticize my dad so unscrupulously. Maybe my mother will always be an exception with my father, so that my mother can bet the rest of her life on my father when he has nothing. It turns out that the love hidden in the details of the older generation is also easy to be knocked.
