planning a funeral gathering

Answer 2

Answer: the correct answer is planning a funeral gathering

Explanation: Once Juliet's body is discovered, Capulet says:

All things that we ordained festival Turn from their office to black funeral; Our instruments to melancholy bells, Our wedding cheer to a sad burial feast, Our solemn hymns to sullen dirges change, Our bridal flowers serve for a buried corpse, And all things change them to the contrary.
