When we were on tenth grade, the young lady "A" messaged me this colossal message saying 'sorry' to me, saying that I didn't merit what she did and said to me, so I pardoned her and now we are great companions. I turned out to be extremely close with young lady "B" about a year after she quit harassing me... she was sorry and we acted like nothing occurred. What's more, the young lady "C" never apologized and never will since she detests me for reasons unknown (she said it herself) however despite everything I pardon ever despite the fact that she doesn't need my absolution.
Try not to hold feelings of spite. Figure out how to excuse individuals and you will see that you will feel greatly improved. Trust me!
