OK we were allowed to hang out with the public schooled neighbor kids, and went to the homeschool co-op meet once a week where we had science, history, and PE classes. We were well socialized. It irritates me a bit to see our neighbors a mile down who homeschool thier kids and DONT let them...
We always used book swaps and stuff, I know that the cost of materials can be reduced. DH pays a lot in Child Support each month so my check is the big one...we couldnt do without it.
