Hey GP dai, Nice explanation. I agree with you except money matters as kalopani and copycat said. Also, there are often misunderstanding that flourish bitterness among friends. For example, 1) Mr. A has helped Mr. B in various ways with and without letting Mr. B know everything, but Mr. B fails to understand the gravity of the help of Mr. A. Instead Mr. B thinks he arose on his own that hurts Mr. A. 2) Mr. A is helpful to Mr. B, but Mr. B does not trust Mr. A can help him as much as he want. So, Mr B seeks help from Mr C. Mr C talks to Mr A about the issue before helping to Mr B, which makes Mr A unhappy. 3) Mr. A used to help in the past. Mr. B asked Mr. A to help him now but Mr. A's situation is not as good as in the past. Instead of trying to understand the problem of Mr. A, Mr. B thinks the other way and starts complaining to others instead of talking directly with Mr. A. Later on, Mr. B realizes his mistake, but has no courage to go and talk to Mr. A 4) Mr. B is in need of help. He has heard Mr. A helped to Mr. C in similar case. He approaches Mr. A, but Mr. A does not want to involve himself in that issue because he was having a lot of trouble with Mr. C in his past helping effort. Mr. B is upset with Mr. A now. These are some classic cases I have seen around.
