Premise: He remained sitting on the floor and held his breath , wondering how she knew that he had come back .<br>If she said ` Peter ' again , he meant to cry ` Mother ' and run to her .<br>But she spoke no more , she made little moans only , and when he next peeped at her she was once more asleep , with tears on her face .<br>It made Peter very miserable , and what do you think was the first thing he did ?<br>Sitting on the rail at the foot of the bed , he played a beautiful lullaby to his mother on his pipe .
Hypothesis: Peter was very happy.
