This story was utterly brilliant. Top, top, top marks, with perhaps a soupçon of disappointment about Another Coming Out Story. (It's a popular theme with a lot of useful ores to dig up, but it's pretty heavily mined these days.)
I'm leaning towards Satan being at the crossroads (because that's both mythologically accurate and also an amusing counterpoint to "It's not God that they're waiting for. It's more personal than that." God, after all, is the ultimate reshaper, the conformity of holy unity, the Singularity of I Am; the Devil, on the other hand, wants to separate you from the herd, to isolate you. God loves everyone; the Devil wants you.) On the flip side, nosebleeds suggest Roswellian alien abductions, as do the bouts of missing time/foggy memories, and comparing SETI's likely fruitless quest with Vladimir and Estragon's anxious awaiting of Godot also amuses me.
It's really not important, of course, and I strongly appreciate the story not forcing the issue.
Also, "Waiting for Godot" is one of the best plays ever, read or performed. (Except for when people try to make it heavy, portentous, and boring and thus somehow more artistic.)
