THANKS for your great post with its similarity in feeling regarding meeting Mr. Culp. I only began feeling guilty and anxious after hovering too long; one wishes to extend respect and gratefulness, not annoyance to him!
Anyway, it's helpful to learn that others share this ill-defined sense of awkwardness and almost embarrassment in the presence of an actor one has held in such high regard for so long, really, decades.
Thanks, Tatia, too, for your supportive post. That was very appreciated.
