It is easy to get caught up in the illusion that words actually mean something. It's one very effective way to stay several steps behind the experiences we are actually having in our lives. The  reality is that words are pointers, they are triggers for a somatic experience in the body, based on a particlaur person associates with the words that are being spoken. 

It is common to think that because a word or set of words produces a particualar experience in us, it does so in everyone else. This is a false assumption - and the consequences can be anything from humorous to dangerous. Consider what it means to a British person who says "I was bloddy gobsmacked!" and what that same phrase means to an American. You, the reader are having a particular experience based on your own set of physiological associations with the phrase.

While this is pretty easy to see with an example like that, it is more challenging when the words being written or spoken are describing something that most would consider as having the same meaning- like "I was really busy today" which meant to one person they got up, got to work, did several things, came home and to another cleaning up the house, taking care of a child, driving to get grocieries. Both have said busy, yet the physiological experience is much different. 

One tool to remember if you want to be a truely effective communicator is to consider that the other person's experience of the words you are using areas opposed to your own.
