Premise: And I 'm glad for that .<br>But I 'm hungry for a violin all the time .<br>And I only come here when the hunger gets too much to bear .<br>I feel as if I ought n't to come even then -- I 'm always saying I wo n't do it again , because I know grandfather would n't like it , if he knew . ''<br>`` He has never forbidden it , has he ? ''<br>`` No , but that is because he does n't know I come here for that .<br>He never thinks of such a thing .<br>I feel sure he WOULD forbid it , if he knew .<br>And that makes me very wretched .<br>And yet I HAVE to come .
Hypothesis: Grandfather forbid them from the violin.
