Well, it's official, school is back in session. I know this for a fact even though I don't have children because I visit my public library several times a week.
To all those parents who work and can't be home when their children get out of school for the day: Please know that your dilemma is recognized. But do the world a favor. If you tell your children to go to the library after school, be courteous enough of others to teach your child or children how to behave in a library. No running, playing hide and seek, talking loud, etc.
In other words, a library is not a daycare and the library staff are not baby sitters. I'm sure that they have plenty to do without having to be responsible for other people's children.
