Who would you let into the house

Last week in the late evening my son knocked on my door in distressed state. We let him in. An hour later a neighbour who been in a equally distressed state since his wife died last year knocked on the door very upset. So we invited him in. We’d told him if he ever needed us to knock but he never had until that night. When they left my husband turned to me and said “ I think we might have broken the rules” At the time I’d never even given this lockdown a thought. I was just worried about both of them. Honestly I don’t think even if I’d have remembered the rules I could have turned either of them away. It’s yet another dilemma. The possibility is that it could happen again. (Hopefully not two people crying on the same night)
What would you do?
