I don't know why she completes me Why I'm the guy of her dreams I don't know why I'm her hero I'm not even sure what love means chorus: Don't let her know she's an angel Don't let her know Don't let her know that you see Don't let her know that she's touching me I'm scared that she'll want to go free I know I've tried to deceive her Tricked her in love with me Pretending that I don't need her Love's full of such mystery repeat chorus Some things are best left unsaid Some things should stay in your head I scare her away with my caution It's better that I take no action repeat chorus Maybe someday I'll tell her Tell her what love means to me Maybe some day I'll show her The guy to make love to is me repeat chorus (2x)
