This is difficult because there are so many families who have both parents working just to make ends meet; they don't have much choice other than to trust their kids at home. It is difficult for single parents, too, not only because they don't have other adult helpers, but public school schedules are crazy sometimes. Just this week we had an early out day so we teachers could have meetings while the kids went home. Parents can't just get work off to attend to children who are sometimes out of school for irregular reasons. That's part of the reason I became a teacher; that is, so I could be off work when my little guy was out of school. It was difficult in the beginning, but now that he's older, he can work quietly in my classroom while I'm in meetings. It's certainly a tough discussion.
