They say what you don't know will never hurt you   What you don't see won't ever bother you at all   So if you see my sweetheart with another   Don't tell me you just make the teardrops fall   Let me go on thinking I'm the lucky one   And deep within her heart she loves me so   If there are unfaithful things that she has done   Please don't tell me I don't want to know      You may think you're doing me a favor   By telling me the things that you have seen   But you're just lighting fuses of destruction   You are just destroying my dreams   Of every reason to believe she's kind and true   And in my heart I think she loves me so   I'd be broken hearted if I heard from you   All the things that I don't want to know   [ fiddle - steel - piano ]   Let me go on thinking I'm the lucky one   And deep within her heart she loves me so   I'd be broken hearted if I heard from you   All the things that I don't want to know
