i don't know if this is true..but there's this part in the song that i think that it's about betrayal.
"Mary had a lamb
his eyes black as coals
if we play very quiet, my lamb
Mary never has to know"
i think it means that she can have something with someone, but if they do things quietly, he never has to know.
i know if you understand what i'm trying to say, it's stupid but it's what i think
