Until recently, I remained a slow-to-develop-maturity-type. So it took until adulthood to realize that my thoughts are not visible.
So, up until then, I suffered many “embarassing moments” from childhood on, not realizing that my facial expressions were NOT giving away my beliefs or thoughts.
For example, some of my most embarassing moments would be waving to someone who I thought I recognized as a friend, but was not her, or thinking someone was talking to me, and wasn’t. Or feeling put out of a game, a social circle, a hello, etc, and actually no one really knew what I was experiencing internally, anyways!
I realize now, nobody knew what I was thinking.
Thank g-d for being a grown up.
