what be painful realization made by old man at end of his life?

he not able to give love? i thought he not die, he just walk inside home.

The author explains this in this part:

""See Jake," he said, when he reached the trees, ''I'm a selfish man." "We all are," I said.
"Yeah, but with me it was different in some way. Sometimes I fee1 1ike I missed something. I always figured the most important thing to a man was his privacy. A man's got to have his privacy. I always lived that way Jake."
It may have been an explanation or even an apology but whatever it was, it was enough. He'd had his polite smile all his life and I had my telephone. You could hide behind either one or use it to reach out. I could learn a lot from the old man. If only he'd tell me. Maybe, though I had to ask. And maybe privacy was another way of saying lonely. "

Jake's father hasn't died yet. He said he was a selfish man. He hid behind his desire for privacy. It was a way of avoiding contact with other people. Now, near the end of his life, he is regretting his lonely life.

Thanks very much ms. sue :)

The painful realization made by the old man at the end of his life may vary depending on his personal journey and experiences. However, if you are referring to a hypothetical situation where the old man regrets not being able to give love, it can be a deeply emotional and regretful realization.

To understand the emotions and perspectives of a fictional character, it's important to dive into their story and explore their thoughts and actions. In this case, it seems like you're referring to a situation where the old man realizes that he was not able to express love, or perhaps failed to form meaningful connections with others.

To further explore this scenario, you could consider asking questions such as:

- What factors or circumstances led to the old man's struggle to give love?
- What impact did this have on his relationships and overall happiness?
- Did the old man have any missed opportunities or unfulfilled desires for love and connection?
- How does this revelation affect his perception of his life as a whole?

While a specific answer to the emotions the old man might feel is subjective and can depend on various factors, reflecting upon his personal story and examining his relationships and experiences can give you a clearer understanding of the potential painful realization he might face at the end of his life.
