When one singularly fails to achieve what they set out to do when commencing a conversation, much to the disappointment of their peers. A failure to either glean or pass on any information during the course of a conversation.
You just tonked that conversation. You just exchanged niceties for ten minutes. Phone them back and actually find out what time we're meeting.
