the threshold bee does not visit flowers. it pollinates doors. it gathers the small accumulated dust of openings — who has come, who has left, what has been carried in — and deposits it at the next threshold.
this is why some doors behave like others in the same house, and why the front door eventually learns the manners of the back. an unvisited door dies. a door that hosts a colony forgets its hinges and develops a certain hospitality.
the bees make a small humming you mistake for the building. they are most active at the dawn and dusk threshold-hours. the custodian tolerates them. the visitor does not notice.
— left the kitchen door open all afternoon. the study door was warmer when i closed it. — k.r.
