They don't do it on their own, you have to take them places, and not have a tablet with them constantly. It takes commitment, but isn't complicated.

To us, its just part of homeschooling schedule... my kids have a rough schedule of story and free time at a library, play dates, seasonal sportsy outdoor things, etc.

Public school parents seem to abdicate this responsibility culturally, so many kids don't know how to talk to anyone outside of a detainment context. Talking to adults that aren't their parents is just as important.

Even if you're not in a position to homeschool because of work/household formation etc you still have to parent like a homeschooler, can't just leave them with the state day in and out and hope for the best.
