There were a few things for which Princess Celestia and Pinkie Pie found common ground. Having contemplated some of her antics around the Princess, Pinkie Pie approached her with a proposition to make it up to her in a manner that could have been described as convoluted and, to a laypony, dangerous. However Celestia had long hoped to try this with another pony after centuries of the matter effectively being taboo.
 
This is why Pinkie Pie was now in a cup of tea the size of a swimming pool while Celestia gave her a rather wry smile. Once this was over Celestia hoped Pinkie would bring this little ritual back into vogue.
