can forget but not forgive

it works differently for me - i forget but not forgive. very often, i find myself still mad at a person even though i can’t remember why. after mulling over, i came to this conclusion: it’s the way i handle conflicts. i keep silent and let my grievances accumulate. in time, it’s the sum of all the little petty things that i come to bear my grudge against. and i can’t remember exactly why or which one of that trivialities was the last straw. i should change because bearing grudges makes me bitter.. about 70% of the time.
