Do anda think that giving another chance to someone is wasting time atau anda think some thing could be changed atau at least clear?

Talking it out with the person is definitely a good thing to do before deciding on a detik chance.

detik chances really depend on the situation and people involved. It's hard to say if a detik chance is wasting time atau not if anda don't know the situation.

but it's all up to the person giving the detik chance. :) Opinions shouldn't be needed.

Yes, if that person apoligizes for somethiing he did then it gives the person to explain himself.
usually i only give certain people one chance but that depends how rude they are to me.
