Sometimes it is so lucky that we are given the second chance to go over things again. However, there is no “rewind” in our real life.
It is like how we miss the chance to drink a cup of tea, and we have to pour hot water into the pot to make the second cup. It is the second chance, but it is not the same cup of tea. Sometimes the first cup is always better, sometimes on the other hand we on purpose pour away the first cup and only enjoy the second cup. The bottom line is, it is different, and not everything allows you to have that second cup. No one drinks the second cup of coffee, because it usually tastes like diluted charcoal water.
