Dear Princess Celestia,
I have recently decided to document what happens when you mix ponies and alcohol. I believe that the best way to observe this would be to have at least one of each species of pony present. Serendipitously, my six friends and I are different species of pony, two of each represented. So, I will use this group, including myself, as those to receive the alcohol. The individual effects on each of us is recorded in the enclosed documents.
Be warned, there may be a few... Shocking reports. Come to think of it, I know there will be. Just... Please don't do anything about what you find in the reports, we didn't know what we were doing.
Your Faithful Student,
Twilight Sparkle
