Okay, so maybe the example above is a little dramatic, but you get the point. Forthcoming implies that something is approaching, in the above example a decision. Forthcoming can also be used to describe a person who is very open and talkative. Some people are forthcoming to a fault. This is where the TMI rule comes into place. TMI stands for Too Much Information, and is an acronym that I use when someone goes overboard in revealing personal matters to me. For instance, if I am waiting outside a restroom, and the previous patron of the facilities walks out and says, "Whoa! That was a rough one," it would be a classic example of TMI. People do not need to be forthcoming about such things!
