Hi Rainwater ~ I too know what you mean. I'm invisible. No one ever knows I'm around. Oh I'm physically there, but it's like they just can't see me. I'm not important ~ I don't count ~ I'm not of anyone's "caliber." It's like that when I shop too - They'll wait on someone who came AFTER me before they'll wait on me. Umm, like - where did I go??? Hello - I'm still here ! It gets frustrating.
I don't feel very intelligent either although my shrink says I am. It doesn't come out of my mouth that I am. I can't complete with these college educated people - I just graduated from high school. And like you, I lose my train of thought and end up standing there looking like an idiot.
Oh well. I might as well get used to it. At this age, its not gonna change.

Just wanted to let you know you're not alone. God bless. Hugs, Lee
