16. A system that automatically responds to messages, comprising: an analyzer that scrutinizes a received message to distinguish one or more disparate parts of the message, wherein the message is sent to a user from another user; a parser that separates the parts into respective bins; an extractor that retrieves sentences from at least one of the bins; a classifier that determines an intent of the message from the sentences, wherein the intent includes an indication value to the user of the cost of responding to the message versus the cost of discarding the message; a reformulator that transforms the sentences into a single sentence indicative of the intent; and a decision component that presents the single sentence to the user upon the indication value exceeding a threshold value, wherein the threshold value is automatically determined based at least upon an inferred current state of the user based upon observation of the user.
