My poor , poor 1st years . Mitsu was n't very energetic today , so he was n't running around , but lots of other boys were . I do n't know what got into them .
Why was Mitsu and the first years so tired ?
- None of the above choices .
 - They are being deprived of sleep .
 - They are hurting from fighting .
 - They are not used to school .


They are not used to school .
