noon
These mischievous pranks were very amusing to Oscar , and he set all the more by Tiger , on account of this trait in his character . The other members of the family , too , seemed to enjoy the sport he made ; and it was easy to see that even old Mrs. Lee , though she pretended to be angry with the dog for his mischievousness , was in reality pleased with the attentions he bestowed upon her and her knitting-work . Oscar 's grandmother usually retired to her chamber , soon after dinner , to take a short nap . One noon , after she had been scolding , with assumed gravity , about the dog 's mischievousness , Oscar thought he would play a joke upon the old lady ; so , on rising from the dinner-table , he carried Tiger up to her bed-room , and shut him in . He wanted to conceal himself somewhere , and witness the surprise of his grandmother , when she should open the door , and the dog should spring upon her ; but it was time to go to school , and he could not wait . It so happened that Mrs. Lee did not take her nap so early as usual that day . When she did go to her chamber , Tiger , impatient of his long confinement , sprang out so quickly , that she did not observe him .
