03 August 2023 i "come back home and find" my toy rocket-launcher moved, the obsession lately is my bookcase (i'm missing some receipts i had there), and the usual hair and powder-residue in the sink and on the counter, on the brass and bogey in the shower. i cleaned up only for later to find -- again -- white powder around the sink: must be the vinegar i bought and used when i came back to clean. Also explains the loud bang around 1913.
My discharge waste-water must be being monitored.
