It is a common experience that when there is no electricity, or we do not have time to cook food we opt for precooked food that is ready to serve. The same way human mind keeps store of prefabricated expressions and ideas very often in the form of idioms, phrases or sayings that we confidently state the moment we are at a loss to come up with an original expression requiring mental effort. The subconscious mind that runs many times faster that the conscious mind does a quick search to pick most suitable expression, idea or thought in response to a situation that calls us to reflect. So to say we speak before we think. While this is an economic practice for the mind for answering routine questions, it can cause embarrassment many a time when we fail to be receptive to non standard question or situation. With age we generally lose this ability of the mind and have to come rush back with an apology.
Very often, when someone is trying to communicate an idea or thought, our minds runs faster than his in anticipating what he/she intends to say, so we interrupt and say” I know what you have in mind” or ‘ what you are wanting to say. If our guess is wrong then nothing can be more annoying to the other person than that! This is a common experience when verbal dual escalates for no real rhyme or reason. So practice to do real time thinking.
