Are you going to apologize for your's government's role in killing Pakistani soldiers and civilians? Why should I have an ounce of sympathy when your own countrymen ask for the blood of Pakistan's. If the Afghan's had any shred of honor then they would have supported Pakistan over India, and accept the Durand Line, while acting as proper Muslim brothers.
Even now the twitter post by your countrymen are abusing Pakistan, so do you actually think I give a flying hoot if a servicemen died. My hatred of Afghanistan has increased in these last few months, this is because, Afghan's only show disrespect toward Pakistan, hence it's time to return the favour.
What would you achieve if I apologize to you? Satisfaction? Anyway, your sensitive heart was hurt today, so if it makes you feel better then I apologize. Happy?
