I’ve done the same thing-made someone believe I saw, heard, or smelled something which in reality I didn’t. I guess I didn’t want the other person to think I was not, hmm, hip? disagreeable? disappoint them? spoil it for them? Particularly, if they are going on and on about a thing and really get animated about it. Afterwards, I felt…the best I can describe is- prickly. And too, my conscience was ringing bells. Not loud ones as with a mortal sin but enough to let me know perhaps that was a little wrong. So, I’d offer it up to the Lord with my heartfelt apologies, also said The Act of Contrition and went on about my business. I don’t think it’s OCD. I am a former director of a mental facility. It’s about always pleasing God. Nothing wrong with that.
Further, I’m pretty sure you’ll be quicker to respond the correct way if given the chance again. I know I have.
