I wrote a letter to an advice columnist about my problem last year. I just read her answer today: "Take a deep breath and be mature and open-minded about your perceived problem. Let sleeping dogs lie. Nobody is going to die if you never find out the truth."
This is good. Now I can rest easy and not worry about this problem. If some people who know about this secret ever ask me or my family why I am not doing anything, I can just show them this answer.
Let sleeping dogs lie. Each word has multiple meanings. Let can mean allow or make. Sleeping can mean sleeping or dead. Dogs can mean the animals or persons who act like dogs. Lie can mean rest or falsehood.
