When should “Mom” and “Dad” be capitalized?

I would like to understand capital usage rules with my mother and father. I believe that my statement below is correct, but please let me know if I am not.

One thing I learned from my father is that it is a good thing to gain trust from children. Dad told me how good my father would be. One day I went to his house and I ran out when my father was not there.

The above paragraph is for me to understand the meaning of capital letters. Let's add a number to everyone as follows.

What I learned from my father (1) is that it is a good idea to earn the trust of children. Dad (2) will tell you how good my father (3) is. One day I went to his house and I ran outside when my father (4) was not there.

This is a place I do not understand well. In this sense I am using "I" to represent possession, but it is not right to say "my father". I do not know what grammar rules are, or whether I am correct.

In this case, instead of saying "Larry", use Dad like the name. Therefore, it must be capitalized

My father was diagnosed with delusional schizophrenia before I met my mother. They hurriedly fell in love - they dated for 6 weeks, my mother went to see my father's psychiatrist, and did he think that his father could get married well and nurture his family I asked. The shrinking of the father tells Mama that he can completely live a normal life as long as he obeys his prescribed care plan. So Mama and Dad got married, they took me and my brother to the world. A completely random thing happened when I was a child. My father was bitten by a brown lady duck. He was sick, went to the hospital and received treatment. Maybe spider bites may not be the most common cause of hospital visits - but they are certainly unprecedented and treatment is straightforward.

My mother thinks that he denied that his father could not treat the psychosis he diagnosed. His psychiatrist warned her as she warned that she should be, and accepted that she failed to establish "normal life" with him. It's really easy and fascinating to blame a spider as all these gambles are placed in front of her. Whether it is a diagnosed mental disorder, temporary mental or mental defect due to sadness, stress or disappointment, we can give more consideration to those suffering from any obstacles I can do it. Millions of people suffer from stigma of psychosis. People send their best lives

I received a letter from my mother and father fifty years ago. They wrote that they are making grape pie. I am confused. I have never heard of grape pies, I do not know what mom and dad have done. Mommy is not a pie maker. Dad is not really a pie maker. They asked. A woman with this moral status, you can not say no to her. She taught at school. She teaches Sunday School. She called. She asked. They agreed. A few years ago, when Merv and I moved, I joined the Deborah Circle. Circle is in charge of grape pie management. Preparation began when grapes were harvested in October a year ago. The day the grapes are ripe. We prepared a church kitchen the evening. We wrapped building paper on the counter and floor and fixed it with paint. In the morning, farmers brought a big box of grapes on the door of the church's kitchen.
