I don't know if it's a yaoi, or which Al they use, but I believe that in this particular story, Al get drunk off of Hoheheim's liquor. After a while, Ed comes in and has this big argument with Al, which results in him being kicked out. As Ed wonders the streets, he encounters a man, who not only calls him "ponytail" but mugs him. Al finds him, and I forget the rest of the story... =_=;
I would love the know the title of this fics, since it's really been about a year since I read it. Any clues or ideas would be greatly appreciated!!
