Making random space intimate by attention alone

As I walk by this guy, I hear him trying to work out a billing snafu on his phone account. He is blinded to my presence by the closed loop of urgency, response from the account rep, his own voice, and he is leaking data into the skyway at an alarming rate. He gives out name, address, bank, phone acct#, etc. I consider moving around in front of him and pantomiming some kind of warning, or alert. But I pass. The moment passes. The skyway passes for privacy for those in the thrall of their own voice.
