Re: wht to do ..
It really really depends on the situation.
For example if I swore at someone for something or acted rudely and later on realised it wasnot their fault and I should not have swore then I’ll say “I am very sorry for swearing at you/acting rudely with you. It was very bad of me. I realised it later on therefore I am very very sorry”. Now if to this they are gonna expect me to cry infront of them and then apologise or beg on my knees and apologise then NO i wont do that because I wont expect that from someone if they have been bad with me but later on apologised. mere liye yehi kaafi hoga ke mistake realise ker li aur maafi maang li.
On contrast if during a fight (khudanakhwasta) I killed someone or broke someone’s leg thinking it was their fault and that I was too angry. And then later on I realise that it wasnot their fault at all and that I shouldnot have acted in that manner then for this even if I have to bend down on my knees and apologise then I will do it because in reality my apologies wont bring that person’s legs back or the child back (apologising to the parents). I have ruined the life (this will all depend on whether I have courage to face them and actually admitt my mistake and apologise)
