Some people just don’t give one last chance after they have decided; some do give. There is a point. Those who give last chance may be are kind or might not be confident of their own decisions. Those who usually don’t give the last chance may be are stubborn or might have pondered enough upon the decision already. And never to forget, circumstances do take charge every time!
I belong to the first category, who usually doesn’t give the last chance! What about you? No need to say, just think about it and know yourself more! By the way, don’t imagine situations; try to get the answer from your behavior in the past where you lived your own shoes.
