instruction:
Read the given message of a sender that is intended to start a conversation, and determine whether it was written by a 'Bot' or by a 'Human'. Typically, bots will have a more disjointed manner of speaking, and will make statements that don't relate to each other, don't make coherent sense, or otherwise appear unnatural. Human will make statements in a more or less coherent and logical way. Since these messages are supposed to be conversation openers, humans will generally start sensibly with a hello or an introduction. Humans may also ask why the other person is not responding. Bots, however, may act as if they are in the middle of a nonsensical conversation.
