Princess Celestia woke up the next day with, you guessed it, a hangover. That was alright with her, she made some of her best decision while intoxicated. There was that one time... actually that didn't turn out that well.
Oh! But there was that one time... no that turned into a Griffin war. But having the Summer Sun Celebration in Ponyville surely was a good decision. Twilight now has friends, and Celestia no longer has to be the protector of Equestria! That calls for a celebratory drink.
She walked over to her dresser and opened one of the drawers. She levitated some glasses and a bottle of Brandy. While she was poring herself a glass, Celestia was glancing over some of the papers on her desk. One piece in particular caught her attention.
Burn Ponyville to the ground
Celestia facehoofed and threw the note in the garbage, "This is why I never make decisions sober."
While debating whether or not to dump the whole dresser in the trash, something shiny caught her eye. Celestia levitated the objects and brought them to her eyes, "Ooo! Pretty, pretty, shiny, shiny!"
She stared at the tickets until she realized the severe lack of alcohol in her system. She took a shot, which cleared her thoughts immensely, and remembered why those tickets were there. She was suppose to give them to Twilight and Spike, but she forgot.
Celestia levitated over a generic invitation to the Gala and the two tickets. She rolled the tickets and letter then sent it off to Spike.
Celestia left her room and walked down the hallway nearing her sister's room. She didn't bother to knock on the door, she just walked right in.
Luna jumped up at the sudden noise and fell out of her bed.
"Luna, you've go one-thousand years of drinking to catch up on. Don't worry, I'll help you."
"And that, Luna, is why you never make royal decisions while sober," Celestia concluded.
Luna's eyes widened and she nodded her head, "We understand now, Tia. We shall make sure we never do anything sober again."
Celestia raised her glass, "To being drunk!"
Luna raised her own glass, "To being drunk!"
The clicked their glasses together then chugged them down. Celestia, being the more experienced drinker, finished her glass before Luna. Celestia put down her glass when a familiar smoke appeared through the window and materialized into a scroll. She opened the letter and scanned the writing.
"That idiot, why didn't she just tell me that in the first place? See, Luna this is what I'm saying, I wrote that first letter while hungover. That's also not good. My judgement was impaired, I forgot to send tickets for her friends."
Celestia wrote some words onto another sheet of parchment, stuffed a few more tickets with it and send it all back to Spike.
"Oh, I do so hope they make the Gala interesting this year. Maybe I should spike the punch?"
