So interested were Rusty and his wife in their children that they failed to see that Chippy, Jr., was growing likewise. Indeed, he now overtopped Rusty by half a head. But the Wrens—both husband and wife—entirely overlooked that fact.
Neither did they happen to notice that Chippy, Jr., was beginning to have a good deal of trouble squeezing through the door. For some reason—due, perhaps, to the way the opening was made—for some reason he could get into the house more easily than he could get out of it.
He said nothing about this new difficulty, not wishing to disturb the happiness of the Wren family, nor find himself out of work, either.
Since he continued to grow from day to day there could be but one outcome. And at last when Rusty came home late one afternoon with a plump insect in his bill he found Chippy, Jr., blocking the doorway. His head peered through the round opening. And his face wore a worried expression.
“Hurry up!” said Rusty Wren. “I want to come in.”
And at that Chippy, Jr., began to struggle to get out. But he couldn’t move either forward or back.
“Be spry!” Rusty said impatiently. “Don’t keep me waiting, boy!”
Chippy, Jr., looked actually frightened.
“I’m stuck fast!” he cried. “I can’t move either way!”
