This episode is supposed to bring out the importance of respect, love and care.
Friend A was attacked by B because of a past relationship B knew little about.
Later friend A attacks B back by doubting whether he is manly or not.
Friend C attacks A by insinuating that A has a mental illness for apologizing whenever he does a wrong. Remember they had had other arguments before in the social club.
Friend A threatens to expose C, this escalates and the other members of the club intervene.
The three friends each acted out poorly towards each other none was right.
We should teach ourselves to restrain from taking advantage of people's weakness or downfalls.
Life is better when we can coexist peacefully and with love.
And Idea is not a fact and therefore if one's idea is not similar to yours learn to attack the idea not the person giving the idea.
If you cannot handle an argument don't bother to be involved in one.
