I don’t feel sorry for Amna. This is like that Urdu saying:
Rani hu-ee diwani, susural walon ko maara eenta pathar, maika walon go ladoo paira )or something like that).
Wrong is wrong, yet the wrongdoers who know the impact of their actions on another’s reputation, plead ignorance and expect their mistakes to be overlooked or forgiven. Where’s holding the person accountable for their actions? Sure, I’ll forgive once, but after that you’ve got to earn back my respect and trust. If you violate it again, no more chances.
In terms of what you should do - next time she’s meethi-meethi in front of her mother, make a point of mentioning her transgressions to her mom. Other than that, avoid her. The only other thing is, don’t stoop to her level - don’t talk about her behind her back and don’t mock her - because that makes you no better than her.
I can’t explain why I feel so sorry for her…I dont know. I’m not condoning her actions at all but she must be truly miserable on a day to day thing to act this way.
