Google search and Google Books helped me write an essay and then Google Drive let me down

I just went to the UPS Store to print out an essay. When I checked Google Drive the final version was not there even though I uploaded it 6 hours ago, so I had to use last night's version. I had a very slim chance of winning with the final version but I am not holding my breath over last night's version. I will stick to sending messages to myself by email from now on.
