Let it go, spouse. Worry not. You are not offering Holy Mass and flubbing the consecration or messing up some other public prayer that involves a specific formula, for Pete's sake. If you, little creature that you are, realize it, do you not believe God already knows all about your innocent mistake and then sees that you see it too? Does He not already know everything there is to know about what you and yours need, want, intend, etc? Just let it humble you and laugh at yourself and how pathetic you are! Silently mention the right person within your mind and move on...
Don't take such things too seriously, my dear.
