i found this poem in megan’s pictures (“a day at the office”) and google found me both the author and the source. (it’s embedded into the muni platform at folsom and the embarcadero in san francisco).

30 cents, two transfers, love
by richard brautigan

thinking hard about you
i got onto the bus
and paid 30 cents fare
and asked the driver for
   two transfers
before discovering that i
   was alone.  

it strikes a chord with me coz i do that kind of thing too, i find myself making two cups of tea when there’s only me to drink them.
