I had a horrible experience last night.
Yesterday morning, I handed in an essay. At 11pm, I realised that I hadn't handed in a digital copy yet (which must be done by midnight). I panicked a little, but realised I still had plenty of time to get on my computer and upload it.
Except... when I went on my computer, I couldn't find it. The only thing I could find in its place was a draft that had huge chunks missing. Luckily, I had printed off a paper copy that was a little too blurry to hand in, so I started frantically typing it back up. Whilst doing that, I realised I'd made some really stupid typos, and kept in some sentences that really should have been taken out. Prior to that, I'd been thinking I had done well on the essay, now I think it is absolutely terrible.
Oh, and there was a "happy" ending - after typing for 15 minutes, I thought to myself "I wonder if for some reason I saved the essay in my Downloads folder?"
And I had! If only I'd thought of that sooner, I wouldn't have had to know that my essay is terrible until I get the marks back.
