My adult sibling (aged 57) lives with our mum (aged 76). My sibling does not work and basically lives rent free with our mum. My mum has asked her to leave her house as she is becoming increasingly concerned about my siblings behaviour in the current pandemic and the risk she is potentially exposing our mum too. Whilst my sibling is not specifically going against current legislation they are doing things which are upsetting our mum such as travelling by train to another town to attend a Uni course one day a week, using public transport, not socially distancing and infrequent face covering use. I am concerned for my mum’s welfare and particularly how worried she is that my sibling will infect her with COVID19. Any thoughts, advice or comments would be really welcome
