What are the main reasons you choose to send your kids to school? Homeschooling is the default, not the other way around. Our education system is new in respect to how old our world is.
When we are kids, we expect so much on our parents. Now that we are older, we are much more understanding and mature. Make it up to them -- tell them how you appreciate their presence. A lot of old people don't think they're needed or wanted and have to be told that their presence is appreciated. This cancel culture today too easily writes adult parents off. We don't write off our parents nor do we replace them. We make sacrifices, at their terms, not ours, if we sincerely want them around.
