The café was getting full and the party next to me was chain-smoking. Didier noticed my bronchial agitation and my aloofness toward the bachelor beside me, so he told me to go downstairs into the "cave". Here is my home, he says, where it is dark, quiet, free of smoke and where I can have a wireless router all to myself. This is all because Katie is his favorite name. Or so he says. What a doll.
