Parents are busy people. If they are working, they are usually not at home   their children return from school. Sometimes it is necessary for a parent to write    after-school note for their children. They sometimes put the note on the kitchen table, the refrigerator,   another place where their children are sure to find it. A note is often a     way to "talk" with a child than using the telephone. For one thing, parents have time to think about   they want to say before they write.     another, the note lists all the information in one place. It is easy to read again and again People often forget all the details that   hear in a telephone call. Finally, cell phones can be turned      or telephone calls not answered. For these reasons, after-school notes are very popular with parents.
