I went back to school a few years ago to become a paralegal; our plan was that I would go back to work soon after I finished last winter. So far this hasn't happened. While I'm not against homeschooling per se, it wasn't what we had planned for the future, so it's not an easy decision to make.

We do a lot of informal "schooling" on the side, so our kids are learning stuff (that they're interested in) all the time, just not necessarily at school.
