My in-laws have a large beautiful home with gardens spanning a couple of acres. We live 10 minutes away with DS4 and DD2 in a more normal sized house that’s mid renovation.
I realised, after talking to a friend recently that we hadn’t been invited to their home in just over 2 years since DD was a baby. We see them quite frequently though, but always out or at our home. In-laws are fit and in their mid 50’s. MIL doesn’t work but does a huge amount to maintain the house and gardens and we usually see her once a week for a couple of hours during the holidays. They aren’t particularly engaging grandparents and prefer to watch them play or for us all to go out for lunch rather than be involved in the playing (which is fair - I hate it too) but overall they say the right things about how much they love the grandkids but I just feel a bit sad that they don’t ever want to see us or the kids at their home.
