The Ropes - Let On lyrics

Since I was a kid I've watched what I've said My tongue's cut and swollen From all the times I've bit I held everything in Played dumb I did Now everyone's sayin' She's so out of it But I know much more than I let on They talk behind my back I don't react The world is just a train And I'm the tracks But when they least expect I'll speak at last They'll all turn and ask "How did you know that?" And I'll say, "I know much more than I let on"
