To marry a royalty, to marry an alicorn, to marry a princess, to marry a very important pony, to marry a high valued Individual~ should I keep going, because I think I still have more different words packing with the same definition.
Anyways, marrying present time Twilight Sparkle, whom is an alicorn. My reaction when she said 'yes' to my marriage proposal, would somewhat be like this.
Well, here's the story, since I do love writing but I don't very much love romantic stories.
Shock as I felt it in the first time after she said 'yes' and as well as over-excitement, joy, the feeling of awkwardness -- since why would a princess marry a simple pony whose occupation is only writing and mostly why would she marry somepony who is mortal, I asked myself that, but it seemed that she is comfortable with it.
And so, we planned our wedding ceremony at Canterlot as how her brother; Shining Armor suggested. Though she didn't want anything too regal or too luxurious; well, as for me, I just want to make her happy -- good thing I'm rich from all of those books I had written.
The decor, the atmosphere, the food and refreshments, and the music... everything, oh, almost flawless, thanks to Rarity that is. Everypony was there, the Royal Sisters too, and to think of it, perhaps all of Canterlot and Ponyville residences were there. It was a day to remember, though mostly I will remember Twilight smiling in joy.
