Am not sure the childcare bubble counts if your socialiszing with the mother unless you live alone and have a bubble with her too and noone else. But as said before its only minor and will soon be allowed anyway.
Am seeing far worse. LA neighbour has just come back from 6 months abroad and as to quarantine for 10 days but as had more visitors round into the house in 3 days than we've had in the last year, then yesterday went out with friends in the car god knows where.
But its not my problem - will keep away, Can only control what we do
