I live in an area where there is total lockdown other than work and essential care etc, kids still at small local school but all out of school activities are cancelled and we are only allowed to go for exercise locally. We live in a small village where there are many old people. A young couple has very recently bought one of the houses as a holiday home for them and their main home is 3 hours away. They have been coming to the house every weekend ie travelling back and forth to do work at the house. It is not essential work, it is decor (I chatted frequently with them before lockdown) but the couple have told someone it is essential work. Would I be being unreasonable to ask them myself what is going on? They will hear the irritation in my voice and this might affect future relations and they will say that they are allowed and that they aren't talking to anyone and therefore no risk.
