The past is done
Regrettably, this scenario is often portrayed in the realm of fiction and is not feasible in real life.
Altering the events of the past is an impossibility, no matter how much one may wish to do so.
While making amends for past actions through apologies is possible, it is also possible to honour the past and learn valuable lessons from it.
Nevertheless, changing what has already occurred remains an unattainable feat.
