My father was quite a secretive guy and he tends to solo everything like the problem he has right now. However, he is quite weak in terms of confrontation. Once someone knows he is lying or anything similar, he will immediately spill out the beans. He can't hold a secret for very long.
"So you knew huh..." my father sighed on the other line.
"Do you want to tell me something that I don't know father?"
"Not now, son. I know I have lots of secrets but I am not going to involve you in this matter. This is my mess and I am going to solve it by myself."
"Father! Don't just -" before I can finish what I was about to say, he dropped the line and only the dial tone remained.
