Years ago I used an agency, one girl kept bringing her child, one I set little traps for, to see if she actually moved anything, she failed. Then they sent me two at a time, they didn’t realise my teenage daughter was at home once, turned up late, left early and watched a lot of television.
Eventually they sent me a lady they had just employed, and she was a marvel, we had a very happy relationship/friendship for about ten years till I’ll health forced her to retire.
In you get a good one, you’re very lucky.
