"'Trees are like children,' said Mrs. Lynde.  'It's dreadful the way they grow up the minute you turn your back on them. Look at Fred Wright...he's only thirteen, but he's nearly as tall as his father.  There's a hot chicken pie for supper and I made some of my lemon biscuits for you.."
-Anne of Ingleside, Chapter 1.
