A.N (September 1985, Sam is 2, Dean is 6 ½)
Dean hated to hear his little brother Sammy cry. Sam sounded absolutely miserable and Bobby wouldn't even let him in Sam's room to comfort him because he was highly contagious, and Bobby didn't want Dean to get sick too.
So while Bobby was checking Sam's temperature, Dean snuck into Bobby's study and took the tape recorder and a wrapped blank tape and recorded a tape on the back porch of him saying comforting things and singing Sammy's favourite songs. Bobby caught him with the tape recorder after lunch and told him off for taking his things without asking, but promised to play the tape for Sam later when tucking him in for the night.
John called the next night to tell Bobby what Bobby had already suspected: a boy in Sam's nursery school class had the mumps and it had been making the rounds of the kids in his class.
