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

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

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

but it's all up to the person giving the سیکنڈ 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.
