Dear World,My son starts school today.It’s going to be stran

Dear World,
My son starts school today.It’s going to be strange and new to him for some time.And I wish you would treat him gently.
You see,up to now,he has been the king of his own room.He has been the boss of the backyard.I have always been around to treat his wounds* and to comfort* his feelings.
But now things are going to be different.This morning,he’s going to walk down the front steps,wave his hand and start on his great adventure*.
So,World,I wish you would take him by the little hand and teach him the things he will have to know.
Teach him there are heroes,leaders and friends in this world.Give him quiet time to think over the mystery* of birds in the sky,clouds in the sun and flowers on the green hill.
Teach him to believe in his own ideas,even if everyone else tells him they are wrong.
Teach him to stand and fight if he thinks he is right.
Teach him never to put a price on his heart and soul*.
Teach him gently,World,but don’t coddle* him,because only the test of fire makes fine steel.This is a big order,World,and see what you can do.He’s such a little fellow*.
Mother
