unfortunately there are some strict rules that must never be crossed. in ANY case.
- you should never entrust your money to anyone (obviously I am referring to those cases in which there is no legal contract/obligation).
- never bet money that you cannot lose.
- you should always play for fun and not to "get rich".
- one can be happy and live very well even "without money". anything can always be fixed, except death
Completely agree with your last statement which states that anything can be fixed except death, there are really a time when I get trapped in situations where it seems like we will never get out from, but if we can just be patient and wait a little longer, a way to come out of such situation will always be made available to us, but unfortunately, some people out of impatience dabble or end up with decisions they or those around them regret for live.
And on never entrusting your money to anyone, this is another good advice, though In the story, the friend to the suicide victim didn't entrust the money to him, it was the suicide victim who collected his friend's phone, then withdrew money meant for the school fees and used it to bet, which he also lost, the friend did not know that the suicide victim had withdrawn his school fees and used it for betting, until he was told.
