However you slice it, both Kit Connor and Rachel Zegler are currently very famous, especially among the younger demographics. I teach college, and Romeo + Juliet was the show that all my students were clamoring to see in the fall. Both appear to be very generous with their time at the stage door, so it's disappointing that boundaryless people take advantage of their goodwill. I completely understand why some actors choose to skip the ritual altogether.
(And to echo what has already been said - I've never been much of a stage door person, but I did it a few times when I was a teenager, in the late nineties. It was quite different than the current setup: few people, no barricades, actors generally leaving within minutes of the show's end. Often actors wouldn't stop unless someone asked for their autograph as many didn't assume there would be anyone waiting for them.)
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
