I, like this character, am a closet brony. I read this and felt every emotion he felt, I cried just from him having sneaking suspicions about something happening. At the end, I stopped, and examined my life, and how pathetic and hollow it is. While it isnt a waste of 15 years to have been taking care of her, he doesnt have much to show for it, i dont think it is fair! This was so sad, I still cry from thinking about it too much, saw the picture version on EQD and it made me cry.
