Have you ever lied inadvertently?

I’m extremely introverted, but it took me a long time to realize this. Now, I will usually say, “I need a bit of alone time.” when I start to feel exhausted. Most people understand, and after a little break, I feel able to interact again.

Before I started saying what I want, I often used some half-true excuse. “I’m tired”, for example – while that is true in a way, it is not the whole truth. The point is, I have also caught myself at outright lies. I would say I had an appointment, for example. I can’t remember deciding to lie, and I only noticed I had lied after the words were out of my mouth.

What’s that about? Do you think I may have managed to fool myself into not noticing those lies? Have you ever done something similar?
