Coldwater cleaning

This single bloke never washed his dishes. You know the kind . These busy "farmer needs a wife" sorts are everwhere around ere.
I knew these blokes can do it tough, but I wasn't lookin forward to the visit. Untidyness I can cope with . But I had heard from others that , when did do the dishes, he did em with coldwater .
Looking everywhere for tell tale signs , it seemed my plate was clean enough .Shiny, infact .
After finishing off a feast of sweet smelling stew , I was feeling quite satisfied until he called out to the dog .
"Cum ere Coldwater" .he said " an have some! ........Thanks Geoff
