Do you remember The Invisible Man? In that H.G. Wells book a scientist invents a way to become invisible.
Well today our youth oriented society has relegated many of my vintage to virtual, if not actual, invisible status :(
Have you ever noticed how many people look through or just ignore you?
Have you ever noticed how older people have adopted the counter strategy of leading with a headlight grin or big smile?
Some say I have lost my filter, but truth be told it is my way of retaining visibility :)
