Jennifer, at As Cozy as Spring was looking for ways to reassure her husband (and herself) that she was actually spending enough time doing school work with their daughter. He was thinking that perhaps "school" should take from 8 a.m. to 3 p.m.
I put it this way:
Tell your husband to compare it to driving down the freeway at rush hour vs. off hours -- you reach your destination so much more quickly without all that added traffic.
One of the beauties of homeschooling is that we get to do so much in the "off hours" ... and traveling can be so much more pleasant that way, can't it?
