The Japanese aisatsu ("greeting") can refer to many things: everyday greetings and salutations, words of apology or congratulations, short speeches, and messages written on special occasions. You can choose whether or not to include such greetings in your child's renrakucho notebook. However, greetings help to build bonds of trust between school and home and help everyone work together on your child's education. So it is important to greet teachers when you drop off or pick up your child at school, or when seeing off and picking up your child at the school bus stop. Sharing your and your child’s life at home, as well as sharing your thoughts, by writing in the renrakucho will mean a good deal to teachers in showing your involvement with the school. This will give you something to talk about with your child’s teachers.
