At least now you know what has been eating you for so long. Like Morpheus said to Neo in the movie The Matrix:
Neo: I can’t go back, can I? Morpheus: No. But if you could, would you really want to?
You can’t unlearn it, it would only hurt you more trying to pretend like nothing has changed. I hope the people in your life will support you through this.
The British Museum can’t even keep its collection from being stolen (ironic), there are 2000 missing artifacts if I remember correctly. Any excuse that “the British Museum can protect the artefacts” doesn’t hold true anymore. They should return the stolen artefacts to be displayed in the county of origin. Egypt has very strong laws to preserve and protect ancient artefacts.
