forgive and forget

This morning i was just thinking is the such thing as "forgive and forget". I remember thats what Nelson Mandela said at the end of apartheid , its easy for me to do that because i did not experiance it how about those people who were  there the ones that lost their lives in the hands of the white men, the ones who spent most their lives in jail fighting for their freedom, the ones who lost family members how do they forget those memories those years of their lives wasted the missing presence of their loved ones. The is only one answer for me to that they cannot forget but they can forgive because those are not memories one can easily forget. I am not aginst the white man i believe that South Africa is moving forward and the are less and less white people who still think that way but now i fear that the is reverse apartheid were black people are teaching their children to hate the white men where our leaders are promoting it with the likes of people like Malema in parliament and i just wonder what that will do for our country. I personaly believe that most of the people that put our people through that pain most of them have died and died with their since and the only person we should let punish them is God.
