Dear Miriam,

I live in a house share in Dublin with three other girls. One of the girls has a sister who has been living in Spain for the past year. She plans to come home for Christmas, but wants to “quarantine” in our house for two weeks before they both go to their family home. My housemate believes that this is the safest bet, as her mother has an underlying health condition, so would be more vulnerable if she went straight home.
