So we have had a lot of illness in the past couple of months. I think we've had more illness in this past short while compared to the whole of last year. Not sure if this is just coincidence but I had a new DCB start in September and it seems this family is always sick. The dad shows up today with his sick daughter in tow (the DCB was fine). She was still in her pjs and the dad looked like the walking dead as he is also really sick. I observed that this was rude but asked that the daughter stay near the door (my preference would have been that she waited outside and I just took the boy). He looked at me like I just told him to f-off. I had spent the previous night disinfecting because I knew the sister was sick and worried about the brother. Do I have a right to ask this? Should I have a conversation with this family about their illnesses?
