I need help to know who said this quote. I don't have a textbook of the play, and I tried to search for it on google but it didn't help any. This is the quote "... most are busiest when they are most alone." Please help thanks.

I searched using Google's advanced search (exact phrase) and I'm told there are no results for this exact phrase.

Therefore, it's not online.

If it comes from R&J, you can go here and scan through the "modern translation" of the play:

Choose R&J, then act I and scene 1, and use only the column on the right. Start scanning; no need to read closely. Go from scene to scene until you find what you're looking for. Once you find it, you can see the original wording in the left column.

Try this site.

So would the answer be: Benvolio?

Yes, sir!

That is Benvolio speaking to Lord Montague in Act I Scene I line 135;however, its wording varies accoring to publisher/translater. I'm an English teacher
