MIL lives a 3.5 hour drive away. She lives alone, but has been driving to pick her OH up and bring him to stay with her for a few days every other week or so. She joked last week that now their ‘visits will be legal’. She then asked today when she can come and stay, as we can be her bubble. I’m totally against it. She already has a bubble with her partner, and she totally flouts the lockdown rules already. Back at the start of lockdown she was going out multiple times a day, and doing stupid things like going on the bus to post a parcel that was entirely non-essential. I feel bad for saying no, I know she is lonely and missing the kids terribly but I just can’t go along with it.
