Answer:
No, memories are not trully forgotten.
Step-by-step explanation:
Even if some memories may be inaccessible for you in some moments of your life, you didn't lose them at all. You can retrieve them later. With a bit of effort, you can find the memories in your brain's unconscious part. To recover these memories, you just need a stimulus, a mental trigger ( a sound, a voice, a smell or whatever), to active the emotions and feelings which will support you to find these memories.
