Yes. And thank you for starting this thread!

I was contemplating starting one on this issue also, but was thinking in terms of people stating specific things that happen that make them feel invisible.

Trite though it might sound, a full week went by at work before someone looked at me long enough to ask if I had gotten my hair cut. Yeah, I did - a week ago...

It not only hurt that no one else at work noticed, but reinforced my belief that I really am invisible... makes me question if my efforts at work are also invisible.
