Brutus' Interrogation -Portia's monologue

Yesternight, at supper, you suddenly arose and walked about, musing and sighing, with your arms across and when I asked you what the matter was you stared upon me with ungentle looks. I urged you further , then you scratched your head and too impatiently stamped your foot. Yet I insisted, yet you answered not, but with an angry wafture of your hand you gave a sign for me to leave you. So I did. This will not let you eat, nor talk, nor sleep. Please Brutus, make me acquainted with your grief.
