Context, context, context

You may have noticed that the meanings can easily overlap. To figure out what is intended, you need to use context. How urgent is the situation? Is it likely to be something the speaker really wants to do? Is it something that's totally going to happen, regardless of anyone's preferences? Most often, a little background knowledge and some common sense are all you need to figure it out. But you definitely need to be aware of the different possible meanings listed above.
