He is nearly 85. Reasonably fit and mobile but heart and blood pressure issues. He lives in France and has been staying with us for a few days for half term. He had a negative test before travelling and has not been out of the house while here. None of us have. I am concerned about him returning to France, where he lives alone, during another lockdown. He would still have to go to the supermarket etc. If he stayed with us he wouldn’t have to do that and he wouldn’t be alone. However, staying with us longer term would mean some adjustments. He has acknowledged he would be happier here but has still booked his return journey tomorrow. I think he would like to stay on but doesn’t want to ‘out stay his welcome’ - he is always considerate of this. What would you do?
