Importance of loyalty in friendship
As I have talked about how important friendship is and how important it's to choose good friends, but know I'll address s much important issue,
If your friend tells you something, not supposing a secret but anything, if they tell you by trusting you keep it to yourself, don't go and tell everyone about it as it might be very problematic for that person.
Now, if you do so then don't think that something like that would not happen to you, you should learn that there is a very very powerful thing know as KARMA and it will hit you if you do dirty to someone. No matter what, no matter today, no matter tomorrow it will hit you.
Also its very important to be loyal to your friend , as not only karma but it also shows what sort of person you are..
