I also want to point out that it is possible to drop homeschoolers off for playdates, classes led by other parents, tutored groups, etc. It's just that the more kids you have learning at home, the less likely you are to be free of them all simultaneously! I do have good friends who will take all three of my younger kids at once, but I don't like to impose that on them very often.
Those who are lucky enough to live near involved grandparents who are retired can let the Grands take care of the kids now and then. I will confess that I am envious of the families who have doting grandparents who volunteer to take the kids fishing, have them help in the garden, or just sit around and talk or play board games. Kids can learn so much from connecting with that generation.
