Sitting on the roof of your home in Ponyville with your love, enjoying the evening sun. A favorite tradition now for the two of you. She looks over at you, and smiles that cocky smile you've grown to love. There's mirth there that still lingers, even though she's a bit older now. She's still confident, but whereas before that smile was a show to keep others from seeing her insecurity, with your help it's become one of true love for herself, and... For you. She slowly reaches over with her forehoof and places it on top of your hand. There's no hesitation. Long gone are the days of her fearing "mushy stuff". She's not afraid to show you her affection. Her magenta eyes capture some rays of the evening sun as they look into yours, lovingly. You could get lost in them for hours. So much of the love she feels for you is portrayed there without a hint of uncertainty or reservation. You smile back at her. She's still as beautiful as the day you came to this weird world of technicolor ponies. Perhaps even moreso. How many years has it been, now? You have to think for a moment. She'd give you hell if you forgot how long ago you became mates. Oh, that's right. 10 years. For 10 years you've been with this mare. You've seen her fail to be accepted into the flight team she loves so much. You've seen her fall hard, overcome with depression. You watched her cry herself to sleep with a sense of lost purpose... But through it all you stayed by her side. She deserves that. She's always been the loyal one, bound by her element. You wanted to give that back to her. Through it all, you stayed with her. A love that had already been there all along was finally able to breathe as it bloomed from the fertile soil your friendship had become. You fell hard for each other, and that love only grew stronger throughout the years. You lean in close, and she does as well, without a second thought. Your lips touch her muzzle and she adjusts to seal the kiss. You bask in the feeling of your love, your connection. She rubs your hand with her hoof as you both savor this simplistic intimate contact. She breaks the kiss and you place your forehead against hers. Eyes closed, you smile. 
"I love you, Rainbow Dash." You say.

Her scratchy, yet somehow maternal voice replies with a deep warmth...
"I love you too, Anon... Happy anniversary."
