There are some memories I don’t ever want to recall again. On the other hand, if I erase those memories, I would also erase the event/person/situation that the memory is based on. Taking it a step further, erasing that event/person/situation would also erase the valuable lesson that I learned as a result.
If the opportunity provides itself to completely erase something from my memory, I would politely decline. The big picture is far more important to me.
