I think I'd at least give myself a second look – I'd probably even consider approaching and starting up a conversation. And I'd probably quite enjoy that conversation.

Unfortunately it's quite likely I'd misread the other me's shyness as aloofness, or even arrogance, and assume he (I?) wasn't interested.

I need to stop thinking about this now; it's kind of a head fuck. Imagining myself trying to pick myself up makes me feel like a character in a Borges story. Or a very, VERY low budget sequel to 'Being John Malkovich'.
