Input: Text: okay, so to preface, i lived in the u.s. for a long time, and we recently moved back to our home country.

yesterday my dad gave me an external hard drive to pass his files from his old computer to his new computer. i didn't know how to that well so i just used apple's built-in time machine backup thing. so anyways i just did it quickly and there was this prompt i didn't understand so i just pressed ok and done. i backed up his computer and then moved his files to his new computer. today, my dad comes in screaming asking if i deleted his files on his hard drive and i didn't know, but then it came to me that that was the prompt. well, it turns out everything he had on that hard drive was all his life's work in the states. every article he published, every document he wrote, every email he sent. 100gb lost. i never saw my dad have a meltdown, but today he did.

basically the world's biggest fuckup.
