This has nothing to do with the actual achievement but: Allgorhythm suggested that you have Lincoln walk around before going to Aunt Lily to initiate the toast to Sammy. There are a number of people Lincoln can talk to. They are only available once you get the task to toast Sammy and before you do the toast. These little vignettes add to the poignancy of the moment and make this, in his opinion, the best achievement of the game.
So cheers everyone!!!!!!
